If possible, provide a phone number 1-888-303-0822 to get a security code via text message. This does not have to be the phone number linked with your account, but it must be capable of receiving text messages. 3. Use alternative verification methods: If the phone number is not working, use the account recovery form to confirm your identity. You may need to submit information such as your complete name, email address, and other account information. 4. Contact Support. If you are still unable to retrieve your account, please contact Microsoft Support for more assistance. You may locate their contact details on the Microsoft Support webpage.
