Unable to Sign In to Apple ID on Apple Watch Series 4 – "Verification failed" Error After Recent Update

Hi everyone,


I'm facing an issue signing in to my Apple ID on my Apple Watch Series 4 (GPS, 44mm) after a recent watchOS update.


The problem:

After entering my Apple ID username and password on the Watch, I receive the following error:

"Verification failed. An unknown error occurred."

This has been consistently happening and prevents me from signing into my Apple ID on the Watch.


What I've already tried:

  • Resetting the Apple Watch and setting it up as new
  • Resetting the password for my Apple ID
  • Ensuring 2FA is enabled on my Apple account
  • Following all steps suggested by Apple Support


I reached out to Apple Support and was eventually told that two-factor authentication is no longer supported on the Apple Watch for my Apple ID. This seems odd, as it worked perfectly until a few months ago.


Questions:

  • Has anyone else seen this error on Apple Watch Series 4 (or other models)?
  • Could this be a bug introduced in a recent watchOS version?


Any help or confirmation from others experiencing this would be appreciated. I hope Apple can look into this and issue a fix soon.

Thanks!

Apple Watch Series 4

I had this issue as well, also with an Apple Watch 4.

I’ve just been on with an Apple advisor and I shared screens.

explained that I had reset the watch 4 times etc.

This time we tried the password, and got the error.

Then the part I hate: I was asked to Turn the watch off using the shut down option.

Waited a few minutes and the turned it back on.


low and behold the old IT trick worked and the password was as accepted.


seems that we auto reset the phone and forget the previous things we’ve been told.

mines now up and running and I feel a little red in the face.
