New: Add Github and Google OAuth to Your Login Form

Allow users to log in to your site using their Github and Google accounts.

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

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

Cotter Login Form now works on Incognito

The issue where Cotter Login Form did not load when cross-site cookies were blocked is now fixed! Please note that some functionalities that rely on cookies (WebAuthn, Social Login) will not work if cookies are blocked.

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.

Redirect to Login Page from Magic Link Approval Page

You can now click on the "Login Here" button after clicking the magic link to continue to the login page without having to go back to your original tab.
