With Cotter, we automatically link the user's existing account with their Social Account, so you do not have to worry about duplicate accounts.

Social Login: documentation

How it works

If a user signs in to your site with Google with an underlying email [email protected]:

Sign up for the first time using Github or Google: Automatically create a user with the Github or Google account's underlying email

Sign up or login with a Github or Google account with an underlying email that matches a registered email: Ask if the user wants to link the two accounts

Login with a Github or Google account that is linked to an existing account: Automatically log in to the account

*Please update the JS SDK to the latest version

Reset Secret Key

We have opened more API endpoints that make use of the API_SECRET_KEY that we issued. Go to your Dashboard > Projects and you can now get a new secret key if you lost it.
