Improve your 2FA verification system

[firefox]

Please improve your verification system. Embedded links on text message or email for verification is very insecure way of verifying users. Please move to a 2fa which sends an SMS or email a six-digit code to enter back in your system to verify a user. Just like what my bank does or Google does.  Plus there should be an expiry time for the six-digit code. I myself do not click on links if I can avoid it.
