We recommend you enter your cellphone number so you can use it for multi-factor authentication (MFA). These days, most apps that store important information, like your banking app, will offer you different ways to safeguard your account by verifying and double checking you're the one logging into your account.
At SideDrawer, we offer advanced security features such as:
Biometric access- Touch ID, Face ID, etc.
MFA- via push notifications for those that have enabled push notifications
Email- the default when you create your account
SMS- we'll need your cellphone number to send you an access code
Additional ways to do MFA will be coming shortly.
