Using OTP via mail with NetExtender

I went through the forums as best as I can but was able to locate an answer. I am pretty new to the Sonicwall environment so I am still educating myself on properly configuring it.

I need to setup 2FA for our VPN users. I managed to get TOTP to work but I want to try to use OTP via mail. I set this option but I cannot get it to work. Im uncertain if this is possible or not.

Im using a NSa 2650 device with as the Firmware. Our users are using NetExtender and are being authenticated through LDAP.

Greatly appreciate the help anyone can provide.

    Hi @DoomRyGuy , as long as your email settings are entered correctly in Log/Automation it will work, test this working by going to the logs menu ( Investigate/event logs ), and select export to file and choose the email option to then send yourself the logs via email.

    if you don't receive the email you have a setting incorrect under the log automation settings (Manage/Log Settings/Automation) or your exchange or mail server isn't allowing the connection

    Thank you Preston with the quick response. I will look into this. But so you know, I may stick with the TOTP option. I did also talk to another member of our group and he recommended to stick with the TOTP 2FA as it offers better security over the OTP with mail..

    Yes TOTP works better in my opinion. The last time I tried email OTP every little hickup in the connection caused a reconnection and another email being sent. So worst case you could get frequent requests to enter the code for disruptions you wouldn't otherwise notice necessarily.
