Safeword token: 5 or S? 0 or O?
If Safeword would have done only 3 usability-tests, they would have seen, that it’s hard to see the difference between the number “5” and the letter “S” or between the number “0” (zero) and the letter “O”.
From some testing until now, I am almost sure that these two characters are always numbers and not letters. But I catch myself regularly pressing the randomizer-button until a set of characters appears that do not contain 5 or 0…
