    Dear @ZGF,

    Welcome to Microsoft Q&A. 

    Thanks for reaching out, and I’m sorry to hear that you’re running into a Single Sign‑On error after entering your password. Based on your description, it seems your password was accepted, but the sign‑in session could not complete the SSO process.

    To understand the issue better, could you please clarify:

    • Which service are you trying to sign in to?

    Which browser or app are you using? (Edge, Chrome, Safari, desktop application, etc.)

    In the meantime, here are a few simple steps that usually resolve this type of SSO error:

    • Try signing in using a different browser or open the current browser in InPrivate/Incognito mode (press Ctrl +Shift + N).
    • Sign out of all Microsoft accounts and sign in again with only your work/school account.
    • Clear your browser’s cache and cookies, then retry (go to Settings > Privacy > Clear browsing data and select Ctrl+Shift+Del).

    Disable any browser extensions that may block cookies or scripts (e.g., ad‑blockers or privacy tools).

    • If possible, try from a different network (for example, a home connection instead of the office network, or mobile hotspot).

    If you’re using a work device, a quick restart can refresh your local authentication token.

    Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.  

    I hope this information helps point you in the right direction. If you run into any issues while trying the steps, or if something still doesn’t feel quite right, please don’t hesitate to reach out again. I’ll do my best to support you however I can.  

    Looking forward to hearing back from you with any updates or additional details. 

    Warm regards,

    To resolve a single sign-on (SSO) error after entering a password, you can follow these troubleshooting steps:

    1. Direct Sign-In: Have the user try signing in directly to the application website using the credentials stored for them. If successful, they should then select the Update credentials button on the Application Tile in the Apps section of My Apps to update their credentials.
    2. Check Password Expiration: Ensure that the user's password has not expired in the application. If it has, they should update their password by signing in directly to the application.
    3. Browser Extension: Make sure that the My Apps browser extension is running and enabled in the user's browser.
    4. Incognito Mode: Ensure that users are not trying to sign in while in incognito, inPrivate, or Private mode, as the My Apps extension is not supported in these modes.

    If these steps do not resolve the issue, it may be due to a change on the application side that has temporarily broken the integration with Microsoft Entra ID. In such cases, Microsoft may work with application vendors to resolve the issue quickly.
