Ability to re-issue backup codes

[brawaru]

Is your suggested enhancement related to a problem? Please describe.

There can be a situation where you lose access to your authenticator and cannot find your backup codes, but still have access to the account. There should be a way to issue new backup codes that replace the previous ones.

Describe the solution you'd like

A 2FA endpoint for Knossos integration that would allow to re-issue the backup codes. The endpoint can require going to the flow akin to what Discord has, for example, where you have to enter the password, and then also enter the code from the e-mail.

Describe alternatives you've considered

• Completely losing access to account. Doesn't found like a good alternative.
