This site is not affiliated with guilded.gg.
This is a third-party site that implements the OAuth2 standard for Guilded accounts.
This site does the heavy lifting of verifying Guilded account ownership and then allows developers to access information through a set of limited scopes that the user explicitly authorizes.
Read up on the documentation here.
You probably won't have to worry about this site until an application redirects you to it. If you're eager to see how it works anyway, you can go ahead and link your account to your browser session here.
You can get help with Authlink in its support server. If you're suggesting a new feature, be sure to check out the todo list and idea board first.
