In what specific situation does this occur?
- In Bitwarden iOS app and the Web version, when you write a ‘0’ (zero), the zero has a strikethrough inside, so it makes it clear it is a zero instead of the letter o or O ,
- In Bitwarden Chrome extension, when you write a ‘0’ (zero), the zero has a strikethrough inside, so it makes it clear it is a zero instead of the letter o or O , and also the zero has the colour blue instead of black, to make the difference even more clear. (*)
(*) I am not sure why this colorization is not used in the Web version, hence why I posted this suggestion: Markup styling for passwords in Bitwarden webversion.
