What are the differences between OAuth and local authentication?

OAuth is a protocol for authorization, allowing third-party services to access user data without sharing passwords. Local authentication, on the other hand, involves users creating accounts directly on your platform, where they provide a username and password.

Which one is more secure?

OAuth is generally considered more secure because it reduces the risk of password theft. Users don't share their passwords with third-party services, and tokens can be revoked.

Are there any downsides to using OAuth?

Yes, OAuth can be more complex to implement and may require more maintenance. Additionally, if the third-party service experiences issues, it can affect your users' access.

When should I use local authentication instead?

Local authentication is suitable for applications where you want full control over user data and a simpler implementation. It's also useful for offline access.
