    Sorry you have to deal with this. You can stay on Bitbucket. Here is what to change before November 30, 2026:

1. Check your GCM version. Run git credential-manager --version on each machine that pushes to Bitbucket.
2. Upgrade GCM. Install GCM 3.0.0 or later. On Windows, install GCM on its own for now.
3. Push once to test. The warning after git push should be gone.

    Switch from Bitbucket to Your product

    Old Git Credential Manager OAuth on Bitbucket Cloud: a change is due by November 30. You can stay on Bitbucket. If you would rather leave, here is how to move to Your product.

    What changes at Bitbucket

    From November 30, 2026, Bitbucket Cloud blocks some Git requests. These sign in with OAuth 2.0 through Git Credential Manager (GCM) older than 3.0.0. Old GCM versions cannot handle rotating OAuth refresh tokens. Git without GCM, and GCM with personal access tokens, are not affected.

    • Blocked from: November 30, 2026 (Atlassian)
    • Affected: Git Credential Manager older than 3.0.0, set up with OAuth 2.0 (Atlassian)
    • Not affected: Git without GCM, and GCM with personal access tokens (Atlassian)
    • Reason: Old GCM versions do not support rotating OAuth refresh tokens, which Bitbucket now enforces (Atlassian)
    • Warning now: Affected users see a message after each git push (Atlassian)
    • Fix: Upgrade GCM to version 3.0.0 or higher (Atlassian)
    • Git for Windows: It bundles GCM; until a new release has the needed GCM, install GCM on its own (Atlassian)
    • Announced: October 13, 2026 (Atlassian)
    • GCM users on OAuth 2.0 before 3.0.0: Git requests blocked from November 30, 2026 (Atlassian)

    You can stay on Bitbucket if you make the change. This page is for people who would rather leave.
