ThreatSwitch is first and foremost focused on your security and privacy. Using multiple emails to log in would expose your account to greater risk, and therefore we don't allow alternative login methods. 

Your account administrator can, however, choose any email as your primary ThreatSwitch login. While we recommend an official, permanent company email address, some administrators have chosen their employee's government or military email address for long-term contracts.

You also have the ability to add a personal email address under 'Contact Details' so your Security Team can communicate using a different method outside of your company email address. 

Want to learn more about what e-mail address you can use? Reach out to your Security Manager or FSO to discuss your options.
