Many people are familiar with the situation of needing to connect a new device to a wireless network, but the router password is long lost or written in tiny handwriting on a sticker that's been misplaced. Fortunately, the Apple ecosystem offers an elegant and technologically advanced solution to this problem, allowing you to share credentials between devices with just a single tap. This feature, known as "Password Sharing," operates at the system protocol level and doesn't require third-party apps or complex manipulation.
The data transfer mechanism is based on a combination of technologies Bluetooth And Wi-Fi, which ensures instant synchronization between your devices. You don't need to know the passcode or spell it out—just bring the devices close together. In this article, we'll cover the system requirements, a step-by-step guide, and possible reasons why the feature might not work the first time.
Using this feature significantly speeds up the process of setting up guest devices or connecting devices that don't support keyboard input. It's important to understand that for the process to be successful, your Apple ID must be saved in each other's contacts, and the devices themselves must be in close proximity. Let's look at the technical details and preparation steps.
⚠️ Note: The password sharing feature only works if your iPhone is already connected to the Wi-Fi network you want to share. Transferring data "out of thin air" without first connecting to the donor is not possible.
Technical requirements and device compatibility
Before setting up, you need to ensure your hardware meets the minimum requirements for the passkey exchange feature to work properly. The Apple ecosystem strictly controls compatibility, so older models, even with updated operating systems, may not be able to activate the feature. The key requirements are the appropriate communication modules and support for security protocols.
To transfer the password, you will need an iPhone running the operating system iOS 11 or later. This limitation is due to the fact that this version introduced secure data exchange technology. If your smartphone hasn't updated to this version, you won't be able to use this method, and you'll have to find the password through other means, such as through your router settings.
On the receiving device side, the requirements are similar. Computer Mac must work on the base macOS High Sierra or later. It is also critical that the modules are enabled on both devices. Bluetooth And Wi-FiEven if you're not currently connected to the internet via Wi-Fi, the radio module must be active to detect nearby devices.
- 📱 iPhone with iOS 11 and above (password donor).
- 💻 Mac with macOS High Sierra or later (password recipient).
- 🔐 Both users' Apple IDs must be saved in the Contacts app.
- 📶 Bluetooth and Wi-Fi modules are enabled on both devices.
Particular attention should be paid to accounts. Apple's security system requires user verification. This means that Apple IDThe address you used to sign in on your iPhone must be saved in your Mac's address book, and vice versa. If you're sharing your password with a guest, their phone number or email address linked to their Apple ID must be in your contacts; otherwise, the system won't display the confirmation pop-up.
⚠️ Note: Operating system interfaces are subject to update. If you don't see the menu items described, check the official Apple documentation or your device's settings for the latest steps, as the layout of elements may change.
Preparing iPhone and Mac for syncing
The success of the operation depends not only on proper technical functionality but also on the correct initial connection settings. Users often forget simple things like unlocking the screen or enabling visibility, which leads to connection errors. Let's go over the checklist of necessary steps before starting the transfer.
The first thing you need to do is make sure the iPhone you'll be sharing the password from is already connected to the target Wi-Fi network. You can't share something you're not connected to. Check the status in Settings → Wi-Fi, where there should be a check mark next to the network name. Also, make sure that the "Cellular Data" function doesn't override connection priority if you're outside the router's range.
The second important step is to check your Bluetooth settings. On your iPhone, go to Control center (swipe down from the upper right corner or up from the bottom, depending on the model) and make sure the Bluetooth icon is blue. Similar steps need to be performed on a Mac: open System Preferences and check the Bluetooth status. Without an active Bluetooth signal, the devices won't be able to "see" each other to initiate a handshake.
☑️ Pre-delivery check
The third step is unlocking the devices. Both the iPhone and Mac must be awake and unlocked when you hand them over. If the phone is face down or on the lock screen, the security system may block the pop-up notification. Hold both devices in your hands and make sure you can see the desktop.
Step-by-step instructions: how to share a password
Now that all the preparatory steps have been completed, you can proceed to the actual data transfer. The process takes just seconds and feels like magic when done correctly. The algorithm is the same for all modern versions of iOS and macOS, but the visual appearance of the windows may differ slightly.
Bring your iPhone (the password source) as close as possible to your Mac (the recipient). The distance should be no more than 10-15 centimeters. On your Mac, open the Wi-Fi menu by clicking the corresponding icon in the menu bar, or go to System Preferences → Network → Wi-FiFind the desired network in the list and click on it to connect.
At this point, a system notification should appear on your iPhone screen asking if you want to share your Wi-Fi password. The notification text will include the name of the device or Apple ID requesting access. You don't need to enter anything manually. Just tap the button. Share password (Share Password) on the smartphone screen.
- 📲 Bring your iPhone close to your Mac (up to 10 cm).
- 🔍 On your Mac, select the desired Wi-Fi network from the list of available ones.
- ✅ On iPhone, tap "Share Password" in the pop-up window.
- 🔄 Wait for the "Done" confirmation on both screens.
After clicking the button, the password will be encrypted and transmitted via Bluetooth, after which your Mac will automatically log in to the network. A confirmation message will appear on both devices. If this doesn't happen, check whether Do Not Disturb or Focus Mode is enabled on your iPhone, which can hide system notifications.
What to do if the window does not appear?
If the notification doesn't appear within 10-15 seconds, try turning Wi-Fi off and on again on both devices. Restarting Bluetooth also helps. Make sure Personal Hotspot is disabled on your iPhone, as it can interfere with the passkey transfer process.
Compatibility table and transmission statuses
To better understand the process, it's helpful to understand how the system responds to various device states. Below is a table describing possible scenarios and the expected system response. This will help diagnose the problem if the standard scenario fails.
| iPhone status | Mac Status | Result |
|---|---|---|
| Connected to Wi-Fi | Requests network | Successful password transfer |
| The screen is locked | Requests network | The window will not appear (unlock required) |
| Bluetooth is off | Requests network | Connection is impossible |
| Not in user's contacts | Requests network | The window will not appear (authorization error) |
As the table shows, the critical factors are screen unlocking and the presence of the contact. Without these conditions, the security system will simply ignore the request. It's also worth noting that transfer is only possible between devices using the same Apple ID, those on family sharing, or if the contacts are backed up to each other.
This feature may not work on some corporate networks or networks with a captive portal (which require additional browser authorization after connecting). It is primarily intended for home and office networks using the standard WPA2/WPA3, where only a static password is required.
Troubleshooting connection issues and errors
Despite the well-oiled mechanism, glitches can sometimes occur. These are most often related to software glitches in the Bluetooth stack or software version conflicts. If nothing happens when you bring your iPhone to your Mac, don't panic. There are a number of steps you can take to troubleshoot the issue.
First, try resetting the Bluetooth module. On your iPhone, go to Settings → Bluetooth, turn off the switch, wait 5 seconds, and turn it back on. On a Mac, you can do this through the menu in the status bar or in System settingsThis is often enough for the devices to rediscover each other and establish a clear connection.
The second common cause is a time or date synchronization issue, as well as problems with iCloud Keychain. Make sure iCloud password sync is enabled on both devices. Check this in the section Settings → [Your name] → iCloud → Keychain on iPhone and in System Preferences → Apple ID → iCloud on Mac.
⚠️ Important: If you're using a corporate device management (MDM) profile, your network administrator may have disabled password sharing for security reasons. In this case, you won't be able to bypass this restriction using standard methods.
It's also worth checking if Personal Hotspot is enabled on your iPhone. When Personal Hotspot is enabled, the iPhone creates its own network, which can block the ability to share the password from another Wi-Fi network. Disable Personal Hotspot before attempting to share.
Alternative ways to connect a Mac to Wi-Fi
If automatic password transfer doesn't work, or if you're near a router but your iPhone's battery is low, you can use other methods. The Apple ecosystem offers several connection solutions, each with its own advantages depending on the context.
One of the most secure methods is using iCloud Keychain. If you've previously connected your Mac to this network and saved the password, it will automatically sync via iCloud. When attempting to connect to a known network, your Mac may not even ask for the password, as it's already stored encrypted within the system. You can check your saved passwords using the app. Bunch of keys (Keychain Access) in the Applications → Utilities folder.
Another option is to use a QR code. Many modern routers allow you to generate a QR code for connection, which can be scanned with an iPhone camera. However, to transfer this code to a Mac, you'll need to either take a screenshot and open it on your phone, or use the Continuity Camera feature if supported by your version of macOS. This method is less convenient, but it works for Android users.
Finally, there's always the classic method—entering the password manually. To avoid errors when entering complex characters, you can temporarily change the password in your router settings to a simpler one, connect, and then revert to a more complex combination. Alternatively, you can copy the password from the settings of an already connected iPhone (available in iOS 16 and later): Settings → Wi-Fi → (i) next to the network → Password) and paste it on your Mac.
Is it possible to share a password if Do Not Disturb mode is enabled on an iPhone?
Yes, it's possible to share your password, but the notification may not appear on the lock screen. You'll need to unlock your iPhone and look at the top of the screen (in the notification shade), where a hidden notification about the password request may appear. It's best to disable focus modes while sharing.
Does this feature work if the devices are in different rooms?
No, to initiate a connection, the devices must be in close proximity (usually within 1-2 meters), as Bluetooth Low Energy is used for discovery. After successfully transmitting the password, the devices can be located anywhere within the Wi-Fi range of the router.
What should I do if I forgot my Wi-Fi password and want to find it on my iPhone?
If your iPhone is connected to the network, you can find out the password. Go to Settings → Wi-Fi, click on the icon (i) next to the network name. In the "Password" field, tap the hidden dots. The system will ask for Face ID, Touch ID, or a passcode, after which the password will be displayed and can be copied.
Do I need internet access to transfer my password?
No, the internet is not required to transfer the password itself. The process occurs locally between devices via Bluetooth. However, verifying your Apple ID and contacts may require brief access to Apple servers, which can be done over a cellular network if Wi-Fi is not yet connected.
