When you are logging in, are you using your Adobe ID (email address) or your company name+account?
If it is your Adobe ID, see the information here to reset your password: Adobe ID, sign in, and account help - I forgot my password
If using your company name+account, see this article for assistance: Troubleshoot locked accounts
Let us know if that does not help, or if you have any questions.
Kind regards,
