If you're trying to recover your Messenger account, there are a few steps that you can take. First and foremost, try logging in with any email addresses or phone numbers that you think might be associated with the account. If this doesn't work, it's possible that Facebook may have disabled the account for some reason - if so, reach out to their support team via the Help Center and provide them with as much information about yourself as possible (name, date of birth etc.) so they can verify who you are and restore access to your account. If all else fails, consider creating a new Messenger account altogether; going through these steps will help keep your data safe from malicious actors online.
