> Whenever I'm creating a 2FA backup on a piece of paper, anxiety hits me every time I cross over certain characters, o/0, v/u, 5/S, etc. I've come to add some fanciness to how I write these characters for this exact reason.

My convention is that I put a dot '.' below every digit (this solves the 5/S, 0O, 8/B etc. issues [the actually problematic ones shall depend on your handwriting]).

If I'm really unsure, I add the NATO/aviation alphabet [1]. There's a 'U', I'll write 'Uniform' (in diagonal, starting from the 'U').

It only requires some discipline. I've done that since more than ten years now, never lost a single 2FA code.

[1] nitpicking about the actual difference between the NATO and aviation codes can safely be send to /dev/null
