So don't put it off until it is too late -- if you haven't already, regenerate and copy TOTP seeds to paper now.

When you set up TOTP on a new account, copy the TOTP seed to paper then and there, resist the "I'll do this later".

If it isn't backed up it doesn't exist.

Corollary (likely unpopular I'd hazard) - hardware token implementations that I can't back up to paper don't exist as far as I'm concerned.
