Signing in, and why support may ask for your account ID
Sign in with Apple or email, and what 'Hide My Email' means for support.
You can sign in with Apple or with an email address and password. If you used Sign in with Apple and chose Hide My Email, osmos sees a private relay address, not your real one. That's fine for the app, but it means support can't find you by your normal email. Your account ID is in Core → Profile; include it when you write to us.
Forgot your password? Use Reset password on the sign-in screen. The reset link opens the app directly; if it opens in the browser instead, open the app and try again from the link.
One account per person. osmos's memory, connections and history are all tied to the account you sign in with.
