I have read quite a few posts about preventing account password takeover from various malicious ways, and many OPSEC measures are there to prevent it from happening.
Consider a case where you face a total blackout or technical failure. Now, you need to log in to your password manager, which requires either OTP on email or TOTP. You don’t have access to the TOTP app because the backup is stored in cloud storage, whose email login also requires OTP.
How would you prevent such from happening?I haven’t found a satisfactory solution or explanation for that yet.
Backup codes. You’re supposed to print them out and put it in a fire safe or something. They’re longer and not time based and valid until you rotate them. With those you can lose everything and still access your accounts.
My KeePass database is also synchronized locally on most of my devices, so even if my server is dead I’m not really locked out, I just have annoying merge conflicts to resolve.
Also, Yubikeys. They’re nice. If whatever blackout destroys your Yubikey, you have much worse problems to worry about than checking your email.
