Only recently discovered that you can save a #TOTP entry (ie #2FA code) in #keepassxc together with the rest of your credentials and, the DB being just a file, you can copy that file elsewhere. 

In doing so, you: 

1) can back it up so you won't get locked out in case you lose one specific device and 

2) can have access to your 2FA-protected accounts *anywhere*, and without having to carry your damn phone with you.

Damn. I now wanna replace *all* of my TOTPs, going as far as claiming loss.
