Delivery options
OTP (SMS, mobile app) default delivery options work perfectly for most users; ESA can also accommodate e-mail delivery.
In ESA Web Console, click Settings > Delivery Options, select Email, click Save.
Email vs SMS delivery Compared to SMS delivery (or usage of provisioned mobile application), email as the means of OTP distribution is slightly less secure because the email can be read on any device the user possesses. This method does not confirm that the intended recipient owns the registered phone (phone number). |
