In the extension for desktop browsers, the password field contains an extension, a character counter, which is especially useful for masked passwords:
Unfortunately, the Android application does not have this very useful functionality. Therefore, when I want to enter the password to the masked fields, I have to find a place outside the range of the cameras and there, on a piece of paper, draw a table with numbered cells and then enter the passwords to them. After logging in correctly, the card must be destroyed, preferably by burning it and stepping on it. I believe this is a difficulty that many people have already encountered and therefore I suggest adding a character counter to the password field in your android app.
