Authentication
Find answers to common authentication issues.
Sign in with OAuth provider doesn't work
This is most likely a settings issues from within the Supabase dashboard or in the provider's settings.
Please read Supabase's documentation on how to set up third-party providers.
Emails aren't sent
This issue may arise if you have not setup an SMTP provider from within Supabase.
Supabase's own SMTP provider has low limits and low deliverability, therefore you must set up your own - and only use the default Supabase's one for testing purposes.
Emails in local development
In local development, Supabase uses Inbucket to capture emails sent during the authentication process.
Supabase redirects to locahost instead of my app URL
This is most likely an issue related to not having set up the Authentication URL in the Supabase settings as describe in the deployment guide.
Domain matters!
If your domain includes "www", ensure you include it in the Site URL and Redirect URLs. If your domain does not include "www", ensure you do not include it in the Site URL and Redirect URLs. If these do not match, your users will not be able to login.
