I cannot log into my 1password account from a Mac running Sierra. The password works elsewhere fine

@glump

My suspicion is you are at the end of life for the OS. Just a thought from one user to another. Apple no longer supports 10.12.x and 10.13.x too. The browser may not be up to todays standards for encryption. I would recommend you talk with my email colleagues. We're not in a position here to access account details and logs.

Please email us using support+forum@1password.com. Be sure to use the email address tied to the account in question.
