MacBook Air issues with password

Hello anjit |,

Thank you for posting in Apple Support Communities.

What is the exact wording of the message that is asking you to enter your password? The reason we ask is, it may not be asking for your user profile. It may be asking for the password to your Apple ID. It could also be asking for a password to a third party app that needs to sign in.

If the prompt mentions a keychain password, follow the information found here: If your Mac keeps asking for your keychain password - Apple Support

Kindest regards. 

Hello anjit,

Thank you for that screenshot. Where are you seeing this message? That will help us determine next steps.

Can you use your Mac password to login to the computer or make changes? If so, have you recently changed that password? If so, let's try restarting as that will refresh everything: Shut down or restart your Mac - Apple Support

If you haven't let's try changing the password, and restarting: Change the login password on Mac

You can use the same password, we just want to see if refreshing this helps.

Cheers!

Hi anjit,

Does the same occur if you start your Mac up in safe mode? Safe mode prevents certain software and items from starting up and also does a basic check of your startup disk. This will help isolate this issue a bit and determine if there may be something in your user preventing you for being able to sign in.

If you are using a Mac with an intel processor,

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2. Release the key when you see the login window, then log in to your Mac. 

3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

Hope that helps!

Thanks, anjit.

From here, it would be best recommended to contact Apple Support. From there they can look further into this with you: Contact - Official Apple Support
