Add a reveal password to MAS pages where password must be entered

Is your feature request related to a problem? Please describe.

Entering long password is quite difficult, especially on mobile with big fingers, and in case of error, the password must be fully entered again

Describe the solution you'd like

Having a reveal password button (an eye icon for instance) would help to track typo on entered passwords and is quite a common practice to forms. Clicking again the reveal button would hide the password, and submitting the form too. When creating an account it's more sensitive I think because if the entered password (even if repeated) is not what the user is expecting (for instance caps lock is on, wrong keyboard map, etc.) the account could be unrecoverable.

Describe alternatives you've considered
Not any I can think of.
