1Password not working to sign in to American Express, only manually typing works.

When 1Password 6 (from Agile Bits store) for Mac is used to sign-in to American Express account, error message says credentials (user id or password) not recognized. When I manually enter same credentials, it works. This also is case with bank accounts (Regions/Capital One).

    Have you tried copy and paste? Or does only actual typing work.

    My Amex account details get filled in with no problems, so there must be an issue with your password.

    One reason why auto-fill does not work but copy and past does work is that the password chosen is longer than the site allows. Many sites will appear to allow you to enter a password that is too long but will in reality truncate it silently. And then the difference in the filling logic between autofill and copy-and-paste means that one works but not the other.

    Of course, this suggestion may be completely on the wrong track in your case.

  • Hi @drjack,

    If you find copy and paste also works as well as manually entering the details can you try saving an entirely new Login item using the steps outlined on our support page How to save a Login manually in your browser please. If danco's hunch is correct you will likely find the stored password in the new item is a truncated version of the first. Given danco is reporting he can sign into Amex using 1Password I'm hoping you find the same but if you don't please let us know.

  • Hi littlebobbytables

  • Greetings @drjack,

    I'm happy to learn you now have a working Login item for this site. Was it the password or was it that weirdly the new item worked but the old one just wouldn't play nicely?

    If you come across any other odd behaviour do let us know :smile:
