Allow usernames or emails to be remembered

Whenever users open a banking app or another app that stores their confidential data, they expect that it's safe and compliant with all security standards. Nevertheless, entering credentials each time they open an application is a huge pain in the neck.

To make their experience less tedious, offer them the Remember Me option. Instead of keeping users logged in forever, it remembers their username or email, pre-filling it and asking for a password only on subsequent visits. It's a more secure method than saving all their information for the next login.

In apps that don't require higher security, the Remember Me function is sometimes used to save users' password, and may even log them in automatically when they open the app. However, it's better to use a "Keep me logged in" option to make it clear that this is the behavior users should expect.
