We are building a custom mobile app and have a requirement to use OAUTH 2 for authorization instead of Pega login screen.
-Is it possible OOTB?
-Any doc related to this implementation(oauth 2 + Pega mobile)?
-Are there any updates related to OAUTH 2 in Pega 7.3 ?
Note: Our desktop application currently uses SAML(i.e Enterprise hosts SSO login page where the user enters their username, password and after successful SSO authentication get's re-directed to pega app).
Pega has enhance OAuth2 for Mobility in 7.3. I would suggest you to refer the release note of 7.3 for Pega Mobility. As per Pega suggestion this is possible OOTB but I have not done this and thus can't confirm. Only read the documents.
