Change phone number on email account outlook

• Go to the Microsoft account security page and sign in with your current credentials.

• Click on “Security” in the navigation bar.
• Select “Advanced security options”.

• Under “Ways to prove who you are”, click on “Add a new way to sign in or verify”.
• Choose “Phone number” and follow the prompts to add your new phone number.
• You may need to verify the new number by entering a code sent to it.

• If you want to remove the old phone number, find it in the list of verification methods and click “Remove”.

What other security options can I add?

• This adds an extra layer of security by requiring a second form of identification (like a code sent to your phone) when you sign in.

• Use an authenticator app (like Microsoft Authenticator, Google Authenticator) to generate verification codes. This is often more secure than SMS codes.

• Add a secondary email address to your account. This can be used for account recovery if you lose access to your primary email.

• Set up security questions that only you know the answers to. These can help verify your identity if needed.

• Generate and store recovery codes. These can be used to access your account if you lose your phone or can’t receive verification codes.

• Regularly check the recent activity section in your account settings to monitor for any suspicious sign-ins or activities.

• Use a strong, unique password for your account and consider using a password manager to keep track of it securely.

• Enable notifications for sign-ins from new devices or locations. This way, you’ll be alerted if someone tries to access your account.

What is an authenticator app?

• You link the authenticator app to your account by scanning a QR code or entering a setup key provided by the service (like Microsoft, Google, etc.).

• The app generates a new code every 30 seconds. This code is unique and time-sensitive.

• When you log in to your account, after entering your password, you’ll be prompted to enter the code from the authenticator app.

• Since the codes are generated on your device and change frequently, it’s much harder for someone to gain unauthorized access to your account.
