The ability to double-check the password is correct during the entering thereof would be useful. Various Android apps have this, and it would be useful to add this functionality in Android and iOS. The functionality shows itself by using an 'eye' icon that when tapped can switch between unmasked and masked.
When unmasking the password, use a fixed-width/monospace font (like a typewriter font) that prevents letter/number confusion (i.e. making clear 'l' is a lowercase L, and 'I' is an uppercase I).
