How to disable Microsoft Authenticator notification

Here's what worked for me, though it does turn off a little more than just that notification.

After getting the notification, don't click on the cross or remove it.

1. Open the notification drawer
2. You should see the suggestion under a title of "Suggestions"
3. Right click on the title "Suggestions" and select "Turn off notifications for Suggestions"

The Microsoft Authenticator prompt is maybe coming up because you turned on Two-step verification.

Try this from the article Turning two-step verification on or off for your Microsoft account :

• Go to Security settings and sign in with your Microsoft account.
• Under the Two-step verification section choose ... Turn off two-step verification to turn it off.
• Follow the instructions.
