Once you've imported your character to a Jagex account, you'll need to log in through the Launcher with your new login email and password.
Heads up:
- Forget about those old RuneScape or Old School RuneScape login details, you'll need to use your new Jagex account credentials from now on
- Logging in via the RuneScape or Old School RuneScape clients will not be possible, you'll need to use the Launcher
- To view any newly imported characters, you need to log out of the Launcher and then log back in
- On your mobile device, you can log in by entering your Jagex account credentials and picking the character you wish to play
- You can still log in to your character using linked third party accounts, such as Steam
