Situations requiring restoration of wireless network access arise quite frequently. An administrator may have forgotten a complex key created months ago, or a new employee may be unable to connect to a corporate resource. Unlike home routers with a simple web interface, the equipment Mikrotik requires a more professional approach to configuration management. Standard viewing methods via mobile apps often don't work here due to the specifics of data storage in the system. RouterOS.
To solve this problem, administrators use a utility Winbox, which provides deep interaction with the router's operating system. This tool allows you to not only view current settings, but also analyze security profiles in detail, check active connections, and generate new encryption keys if necessary. Understanding the password storage structure in Mikrotik critical for any network engineer.
In this article, we'll walk you through a step-by-step process that will allow you to quickly find a forgotten password. We'll cover working with the wireless module interface and delve into the nuances of profiles. security-profile and discuss methods for protecting your configuration from unauthorized access. You'll learn to confidently navigate the menu. Wireless and understand where exactly the key you need is hidden.
Preparing the workspace and connecting to the router
The first step before tweaking any settings is to ensure a stable connection between your computer and the router. To do this, you'll need the software installed. Winbox, which can be downloaded from the manufacturer's official website. Connection is possible either via a network cable (LAN) or wirelessly if you already have network access but don't know the password for the new devices.
Run the utility and in the field Connect To Enter your device's IP address or its MAC address, which is displayed in the neighbors list. If the network was previously configured correctly, authorization will be successful after entering the login (by default). admin) and password. It's important to understand that access rights must allow reading the wireless interface configuration.
⚠️ Warning: If you're connecting wirelessly and accidentally change the encryption settings or channel, your connection to the router may be immediately lost. Always have a LAN cable ready to restore access.
After successful authorization, the main program window will open. The interface may seem overloaded with numerous buttons and tabs, but we're interested in the specific section responsible for the radio module. Make sure the version is Winbox compatible with your firmware version Mikrotikto avoid menu display errors.
Navigating the Wireless Interface
To find the necessary data, we need to go to the wireless interface management menu. In the left toolbar, find and click the button labeled WirelessA window will open listing all available radio modules for the device. On most home and office models, the active interface will be the one named wlan1 or wifi1.
Select the desired interface by double-clicking or clicking the button Interfaces In the window that opens, if the list is empty, you'll see a detailed settings window for the selected radio module. It displays the current operating status, frequency range, channel width, and, most importantly for us, the security profile.
Please pay attention to the tab Wireless at the top of the interface properties window. This is where the basic operating parameters of the access point are located, including Mode (operating mode) and SSID (network name). However, the password itself is not stored in cleartext here, as it is tied to the security object.
The key element for us is the field Security ProfileBy default it often has the value default, but in complex configurations, multiple profiles may be created for different purposes. We need to access the settings for this specific profile to view the encryption keys.
Finding and viewing a password in a Security Profile
Once you've defined the security profile name in the interface settings, you need to go to the profile management menu. In the main window Winbox select a menu item Wireless, and then go to the tab Security ProfilesAll profiles created in the system are displayed here.
Find in the list the profile whose name matches the one specified in the interface settings (most often this is default). Select it and click the edit button (pencil icon or double-click). The profile properties window will open, containing all encryption parameters.
In the window that opens, we are interested in the fields WPA Pre-Shared Key And WPA2 Pre-Shared KeyThese fields store the password for your WiFi network. By default, the text in these fields is hidden with asterisks or dots for security purposes. To reveal the characters, click the button with the eye or arrow next to the input field.
After clicking the hide/unhide button, the asterisks will be replaced with readable text. Now you can copy the password, write it down, or simply visually check it. Please note that letter case is important, so copy the key carefully, without any extra spaces.
☑️ Check security settings
| Parameter | Description | Where is it used? |
|---|---|---|
WPA Pre-Shared Key |
Key for the WPA encryption protocol | Old devices, legacy mode |
WPA2 Pre-Shared Key |
Key for the WPA2 encryption protocol | Modern smartphones, laptops |
Authentication Types |
Authorization types | Determines the available methods (WPA/WPA2) |
Unicast Ciphers |
Data encryption algorithm | Usually TKIP or AES |
Analysis of encryption settings and protocols
While you're in the security profile window, it's useful to take a look at other settings that affect the stability and security of your connection. In the section Authentication Types The protocols used must be checked. For maximum compatibility and security, it is recommended to leave only wpa2 psk.
Parameter Group Encryption And Unicast Encryption define traffic encryption algorithms. The most reliable and modern standard is aes ccm. If you have selected tkip, wireless network speed may be limited and security may be compromised. Modern devices prefer AES.
It's also worth checking the settings Management ProtectionThis setting protects network control frames from interception and forgery. Enabling the mode required may cut off very old devices, but will significantly increase the network's security against deauth attacks.
⚠️ Note: Changing the encryption type (for example, from TKIP to AES) will require all clients to reconnect to the network. Ensure all important devices support the selected standard.
If the password field is blank, it means the network is in open mode or the password is set elsewhere. However, in 99% of cases, the key is specified in the WPA/WPA2 fields. Don't forget to save your changes by clicking the Save button. Apply or OK, if you made any edits.
What is PMKID?
PMKID (Pairwise Master Key Identifier) is an identifier used to quickly reconnect clients to the network without a full handshake. In Mikrotik, these settings are also located in the security profile and may affect compatibility with some Apple and Android devices.
Checking active connections via the Registration Table
Another way to ensure that the settings are correct and to see who is connected to the network is to use the registration table. In the window Wireless go to the tab Registration (or click the button Registration Table). This displays a list of all devices that are currently online.
Double-clicking any device in the list will open a detailed connection status window. This window displays the client's IP address, signal strength (Rx/Tx Rate), connection uptime, and, importantly, the security profile used. This helps understand which profile is working for a specific client.
If the device appears in the list but the internet isn't working, the issue may not be with the password, but with the DHCP or routing settings. However, if the device isn't listed, it hasn't been authorized, and the password you entered (if you're trying to connect with a new device) is incorrect or doesn't match the profile settings.
Use the button Kick (kick icon) to forcefully disconnect from a specific client. This is a useful feature for administrators, allowing them to reset a frozen connection or restrict access to an unwanted user, requiring them to enter their password again.
Password change and security measures
If you find that your password was too simple or has been compromised, you need to change it. In the same window Security Profiles, where you looked at the key, just enter the new value in the fields WPA Pre-Shared Key And WPA2 Pre-Shared KeyAfter pressing OK the changes will be applied instantly.
Remember that after changing your password, all devices will lose connection and will require a new key. Prepare a new password for your phones and laptops in advance. It's a good practice to use a password at least 12 characters long, including numbers and uppercase and lowercase characters.
For additional protection, it is recommended to disable the protocol. WPS, if it's enabled. In Mikrotik, this is done via a command in the terminal or by unchecking the corresponding settings, as WPS vulnerabilities allow attackers to recover the password by brute-forcing the PIN.

Don't forget to update your firmware regularly. RouterOSDevelopers are constantly patching vulnerabilities that could allow remote access to configuration or passwords. You can check for updates in the menu. System -> Packages -> Check for Updates.
⚠️ Note: Interfaces and menu item names may vary slightly between different versions of RouterOS (v6, v7). If you can't find an item, use the menu search (Ctrl+F) or refer to the official documentation for your software version.
Frequently Asked Questions (FAQ)
Is it possible to view the password if I don't remember the login and password for Winbox itself?
Unfortunately, no. Administrator rights are required to access the configuration via Winbox. If the password is lost, the only way to regain access is to physically reset the device using the reset button on the device. This will completely lose all settings and require reconfiguring the router.
Where is the password stored if an external RADIUS server is used?
When using external authentication (RADIUS), passwords are not stored in the Mikrotik security profile. In this case Security Profile Configured to use RADIUS, and password verification occurs on a remote server. You need to access your RADIUS server's database.
Why is the password field empty even though WiFi is working?
This could mean the network is open (Open System without encryption) or a macro or script is being used to dynamically generate passwords. Also, check if you're using Guest Network Isolation or Captive Portal (Hotspot), where authentication occurs via a web page rather than a WiFi dongle.
Is it safe to store a password file (.backup) on my computer?
Mikrotik backup files (.backup) can be password-protected when created. If you don't set a password on the backup, anyone who gains access to the file will be able to restore the configuration, including WiFi keys. Always encrypt your backups and store them in a secure location.
