I remind you that Lemmy.world has recently implemented the ability to enable two-factor authentication.

To enable it, go to your profile settings and find the 2FA button at the bottom. Once you click on “Save” the page will reload and you will have a new “2FA installation link” button that will allow you to save the authentication seed.

Remember to always save the seeds and/or QR codes of accounts with two-factor authentication. Many password managers like Biwarden or KeePassXC allow you to save 2FA codes. However, this would mean that together with the credentials such as email and password there will also be 2FA creating a single breaking point which in some cases is not convenient.

An alternative is to use 2FA applications such as Aegis, FreeOTP, and others (I would avoid Authy because it requires a phone number) or use keys such as Yubikey and the like.
