Logging In | "Save Password"
When you log in to your RingCentral Phone for desktop or for mobile and tick/tap Save Password, the app saves the password so you do not have to re-enter it when logging in. The app will remember your login credentials until you manually log out of the app. This means that you will be logged in automatically when you launch the app even after your restart your device.
If you want to log in with a different extension, you will need to go to Settings > Logout.
