Handling Multiple OAuth Providers with the Same Email

In my project, I am using both Google and GitHub as OAuth providers. Suppose a user signs up using the Google provider, and later tries to sign in using the GitHub provider with the same email address.

  1. Does Appwrite automatically merge these accounts?
  2. Or does it create two separate accounts for the same email?
  3. If merging is possible, how does Appwrite handle the provider UID and existing session data?
TL;DR
Solution: The Appwrite does not automatically merge accounts for the same email address when using different OAuth providers. It will create two separate accounts. If merging is necessary, the developer will need to handle the provider UID and existing session data manually.

  1. Yes
  2. No
  3. the provider UID is stored in the new session and identity.

Maybe this will also give you more info: https://appwrite.io/docs/products/auth/identities

TypeScript
const session = await account.createSession({ userId, secret });
console.log("session", session);

output :
