Cannot switch accounts on Qodana Cloud: logout signs the previous account back in

Problem

After clicking Log out on Qodana Cloud and then Sign in, no login form appears. The previous account is signed in again automatically, which makes it impossible to log in with a different account.

Cause

Qodana Cloud delegates authentication to JetBrains Account. The Log out button ends only the Qodana Cloud session. There is no Single Sign-Out across JetBrains services, so the JetBrains Account session stays active. In addition, a separate session exists on oauth.account.jetbrains.com, and it may survive a logout on account.jetbrains.com.

On the next sign-in attempt, the OAuth flow finds the surviving session and authenticates silently with the previous account, so the login form never appears.

Resolution

To switch to a different account:

1. Log out on Qodana Cloud.
2. Log out on account.jetbrains.com.
3. Open oauth.account.jetbrains.com and log out there as well. This session is separate from the previous one and is the step most often missed.
4. Log in to the desired account on account.jetbrains.com, then sign in on Qodana Cloud.

Alternatively, an incognito/private browser window allows signing in with another account without ending the existing sessions.
