OAuth 2.0

Also known as: OAuth 2, PKCE

The authentication protocol X uses to grant third-party apps permission to post on your behalf without sharing your password.

In depth

OAuth 2.0 is the industry-standard delegated-authorization protocol. When you connect a tool like AutoTweet to X, OAuth lets the tool publish posts using your account without ever receiving your X password.

X's OAuth 2.0 implementation uses PKCE (Proof Key for Code Exchange) for additional security. You can revoke any OAuth-connected app from X Settings → Connected accounts; the app immediately loses the ability to act on your behalf.
