OAuth is the standard way a mobile app gets permission to act on a user's account without handling their password. The user signs in with the provider, and the app receives a token that grants limited access.
On mobile, the secure pattern uses an in-app browser flow with proof-key protection (PKCE) and a redirect back into the app. Common mistakes are embedding a client secret in the app, where it can be extracted, and accepting the redirect without checking it. Both are visible in testing.
