Sign in to GuildOS

The site's front door: you sign in with your Discord account.

What it does: Every sign-in button on the site leads to this page. You sign in with Discord, with no new account and no password, and go back to where you were. It is through Discord that the site knows which guilds you can see.
Who sees it: Anyone. Whoever is already signed in does not even see the page: they go straight to where they were going.
Where to find it: In Sign in, in the corner of the header, or at guildos.me/entrar. It is also where someone goes who tries to reply to a raid through the link without having signed in.

If you have already signed in, the page asks nothing and sends you straight to where you were going.
After signing in, you go back to the page you came from. An address that leads outside the site is never followed: in that case, you land on Your guilds.
If you cancelled on Discord and tried again, you still go back to where you were going, for example to the raid from the link you opened.
Coming from a raid's link, the page says which raid you are going back to, with the day and time in your time zone.
The site asks Discord for your name, your avatar, the servers you are in and your roles in them. Never your email or your messages.

“Discord did not confirm” appears when the Discord window is closed before authorizing, or when authorization is denied. Nothing was saved: just try again.
