PasswordExpired

This workflow will send a Microsoft Teams message through Flowbot when a user's password is set to expire in 14 days

Guide to Setting Up "Password Expired" Flow in Power Automate

Overview:

This guide will walk you through the process of setting up the "Password Expired" flow in Power Automate. This flow notifies users when their password is about to expire.

Prerequisites:

  • Azure App Registration.
  • Power Automate account with a premium or per-user plan.
  • Ensure you have enough API calls for this operation.

Step-by-Step Instructions:

  1. Reoccurring Trigger Setup:

    • Set your notice on a reoccurring trigger.
    • Configure the trigger to recur every day.

  2. Setting Up Variables:

    • varNumberDates: Defines when you want the notification to start.
    • varPassValid: Input the duration (in days) for which the password is valid. Example: 90 days.
    • varexpirationDate: Stores the expiration date. It's a combination of the password's valid duration and the last reset date.
    • vartenantID: Retrieve this from your Azure Active Directory.
    • varclientID: Input the value from the app registration you created.
    • varSecret: This is where you input your secret key.

  3. HTTP Request Function:

    • No changes are needed for the "Get user data" function.
    • This will list out the required information.

  4. Composing and Parsing JSON:

    • Use the compose function to display the calculated values.
    • In the "Parse JSON" step, set it to ignore if a display name or email is null.
    • This step uses the user principal name for verification in the subsequent steps.

  5. Concurrency Settings:

    • In the "Apply to each" loop, you can set it to run concurrently for up to 50 operations or dial it down if needed.

  6. Setting Expiration Date:

    • Perform a calculation by adding the expiration last day's date to the number of valid days to get the expiration date.

  7. Conditions and Notifications:

    • Use conditions to check if the password expiration is less than or equal to a specific number of days (e.g., 14 days).
    • If the condition is met, a message will be sent to the user via Power Automate. Otherwise, no action is taken.

  8. Posting Messages in Chat:

    • Use the "Flowbot" to post messages. If done as a user, it will attach to a specific user, but as Flowbot, it appears as a Power Automate message.
    • The recipient is determined using the user principal name from the Graph API call.
    • In the message body, notify the user about the password expiration date and convert the time from UTC to your desired timezone.

  9. Testing:

    • The flow has been tested with 2700 users and takes approximately 37 minutes to complete, sending batches of 50 notifications at a time.

  10. Caveat:

  • Ensure you have enough API calls to execute this flow.
  • A premium or per-user plan is needed due to the HTTP connector.

Conclusion:

This "Password Expired" flow is essential for organizations to remind their users in advance about password expirations. Ensure to test in your environment and adjust settings as necessary.
