Registered commenters can log into their account several different ways using a register username or email address and password.
Using the Disqus Login page:
Through the embed:
Through the Disqus.com homepage:
Using a social login through the embed
Disqus offers several social login options (Google, Twitter, and Facebook), which allow users to create or authenticate with a Disqus account connected to these services.
You may continue to use a social account to log in, even after being prompted to set a password.
Some sites may use what is called Single Sign-On (SSO) which allows you to comment on Disqus through their own account system.
Sites using SSO can often be identified by the SSO login button found on the embed, shown above
If you're having trouble logging in, we'd recommend contacting the moderator of the site in question. Since this is a completely different account system from Disqus, they will be able to better assist you since they have access to the user database for which you're trying to sign-in.
If you're having trouble logging in as outlined above, kindly see our Login Help documentation for troubleshooting steps.
