We are seeing multiple attemtps trying to log in account and couldn't log in OneDrive.

Please have a look and protect your users, shutting people from logging in is not the way to protect your users.

Bad products!

    Hello,

    Microsoft cannot prevent others from "ATTEMPTING" to sign into your account. If they know your username/email address, anyone can attempt to sign in.

    What Microsoft can do is providing you with the necessary tools so that you can use them to protect your account.

    Please go to your account https://account.live.com > Security, and review the log in activities, are these failed attempts, or actual successful log in?

    You can always change your password, and make sure you have two-factor turned on, and it is always better to use authenticator app as well.

    In addition, if you want to take one step further - Go to your Microsoft account online https://account.live.com> Sign in > Your info > Sign in preference. Add an alias - You have two options here:

    Create new: this will allow you to use the native domain outlook.com to create a new alias.

    Add existing: this will allow you to add a 3rd party email address, such as yahoo, gmail, as long as they are not already associated with another Microsoft account.

    Once added, make this new alias your primary alias, do NOT delete the old alias. Then at the bottom, click on "Change sign in preference". On the next page, uncheck the box for the old alias. This means, from now one, the old alias cannot be used to sign into your Microsoft account, but it can be still used to receive emails, etc.

    If you are experiencing multiple login attempts and issues with accessing OneDrive, it may indicate a security concern such as unauthorized access attempts. Microsoft provides several security measures to protect user accounts, including monitoring for unusual sign-ins and implementing multi-factor authentication (MFA).

    To enhance security and protect your account:

    1. Enable Multi-Factor Authentication (MFA): This adds an extra layer of security by requiring a second form of verification.
    2. Monitor Sign-In Activity: Keep an eye on your account's sign-in logs for any unusual activity, such as failed authentication attempts or sign-ins from unfamiliar locations.
    3. Use Strong Passwords: Ensure that your password is strong and unique to prevent unauthorized access.
    4. Contact Support: If you continue to face issues, consider reaching out to Microsoft support for assistance in securing your account and resolving login problems.

    It's important to address these security issues promptly to protect your personal information and ensure the integrity of your OneDrive account.
