All SplashID Safe 8 users can change their email ID on the mobile app:
Tap menu button (top left) --> Settings --> Change Email (for our iOS app)
Tap menu button (top left) --> Settings --> Account info -- Change Email (for Android app)
Once you change it on one client app, it will update automatically on the other client apps when you login next time - this means ALL other mobile/Desktop apps you use, plus Web app too in case Cloud Sync is used.
NOTE: Changing a SplashID Safe account's email ID via Desktop or Web apps is not recommended, as it might cause side-effects, such as some of your apps not being able to login any more.
NOTE #2: If you want to change your SplashID Safe account password, please see here:
