What is Duo?
The Duo is a two-factor authentication system that helps companies improve their security by confirming user identification, building device trust, and ensuring privacy when connecting to company networks and apps.
Multi-factor authentication (MFA) remains robust while contributing to the security of standard password usage. The total amount of MFA authentications using Duo increased by 38% in the previous year.
MFA authentications are becoming more widely used worldwide, with countries like Canada, the Philippines, Japan, India, and Ireland leading the charge. This shows that more nations are overcoming the challenge and protecting their systems from contemporary hazards.
Why Is It Important to Remove My Phone Number from Duo?
You might want to delete your phone number from Duo for the following reasons:
Safety
When you no longer use Duo or the phone number linked with it, eliminating it lowers the likelihood that someone will get unwanted access to your account. You cannot give someone access to your previous phone number and expect them to get verification numbers for them to log in.
Security of Information
Removing the phone number indicates that no one will be able to find you on Duo merely by knowing your phone number. If you wish to limit who can get in touch with you via the app, this can be helpful.

What Happens When I Remove My Account from Duo?
When you deactivate your phone number from Duo, its effect varies depending on whether you entirely cancel an account or just remove the phone number itself:
Removing the Phone Number Only:
