Have Your Login Info Handy
Make sure you track down all of your login information.
First off, you'll need a Samsung account to join the Galaxy S10 Android 10 beta. If you don’t have a Samsung account, you can create a new one on Samsung’s website.
Creating an account only takes a few minutes and you'll need it when you go to sign up for the beta via the Samsung Members app.
After you install the Android 10 beta on your phone, there's a chance that the process logged you out of some of your apps and services.
Make sure you know all of your passwords and logins before you install the beta on your phone. Otherwise, you might have to waste a bunch of time tracking down or resetting your login info.
