Works for google (should!) but man there are some platforms that don’t expose the Totp code, or let you redisplay it! Sometimes they make you remove the old one before you can make a new one, too.

Few, but screenshot the qr code and print it out.

Even Facebook supports totp it's just well hidden.

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".
