Add a feature that displays the password in the account settings so it can be recalled for login on a 2d/3rd device
What is the point of the password if it can be simply shown in the application/service it's for? I would want more protection like 2FA added to the accounts so that a simple password wouldn't be enough to access it. This coming from a person who has personally experienced leaks and breaches related to services like Adobe, Yahoo, Steam, Google and Dropbox to name a few. All because of a simple one layer password protection.
Use products like Dashlane, RoboForm, LastPass or Bitwarden to store your passwords and other important data. They have dedicated and secure platforms for this and they all work on all platforms. They can also generate very good quality random passwords.
