I store my mechanically generated passwords in 1Password. And I do not use the password in any way.
In such a case, does it make sense to activate TOTP? In my immature opinion, TOTP is only effective if you are using the same password for multiple websites. If this is incorrect, could you please tell me when TOTP would be useful?
Whether it’s the same password you use for everything, or a different password for each individual service, a time based one time password will increase security by requiring a potential hacker to have access to your device or some well-kept secrets in addition to your password. Lacking TOTP, you reduce the amount of hurdles required to get into your account.
