OAuth 2.0 Flows
OAuth 2.0 supports several different flows or methods for obtaining an access token. These flows are designed to cater to different use cases and security requirements.
Authorization Code Flow
The most commonly used flow for web applications with a backend server.
Implicit Flow
Used for single-page applications (SPAs) where the client cannot securely store credentials.
Client Credentials Flow
Used for server-to-server interactions that are not associated with a specific user.
Resource Owner Password
Direct authentication using username and password. Not recommended for most applications.
Device Flow
Used for devices that cannot easily input authorization codes.
Refresh Token Flow
Used to obtain new access tokens when the current one expires.
Passwordless Flow
Authentication without passwords using email or phone verification.
Multi-Factor Authentication
Enhanced security with multiple authentication factors.
