1. You actually enter the wrong password (yes, this happens more often than you think)

Before digging deeper, check the obvious: You are definitely entering the correct password.Errors here are not only in typos, but also in hidden symbols. For example:

Function Private Wi-Fi Address (Private Wi-Fi Address) in iOS 14 and newer is designed to protect privacy: it randomly changes MAC address yours iPhone when connecting to the network. However, some routers (especially older or corporate ones) interpret this as an attempt to connect a new device and block access, displaying an "Incorrect Password" error.
