2FA/MFA should be a mandatory feature when securing a cloud accessible account. Had I known this limitation, I would not have purchased a TP-Link product. Returning my router for this reason. 

We need 2FA (Microsoft Authenticator, etc ..) to secure tp link id login. Definitly. And quickly !

This is required to secure every access using this id : Deco App, web site, etc

The problem exists 2 years on from the first post in this thread. Time to return the Deco.

They just dont care about the support.
