Bitbucket Login with Web3Auth


Bitbucket login can be performed in various ways, depending on the use case. We have demonstrated this with Auth0, but this can be done with any other Federated/JWT providers.

Set up Bitbucket via Auth0

  1. Create a verifier for your Auth0 application by selecting Auth0 as the Login provider from this modal. Bitbucket - Login Providers list on Web3Auth Dashboard

  2. Select the Other as the Authentication Type based on the dropdown. Bitbucket - Auth0 Authentication Type list on Web3Auth Dashboard

  3. Enter the Auth0 Client ID and Auth0 Domain from your Auth0 application. See how to create a new Auth0 application here.

  4. Add the Bitbucket Social Connection to your Auth0 application.

  5. Click on the Create button to create Bitbucket Custom Authentication via Auth0 verifier.
