Hello @Abhishek Dewan,
exactly this feature for the same reasons as @Fadi I would also like to see in Enpass. It's no secret that a password is no longer considered secure these days. Also, the option of a key file is better than just a password, but as @Fadi notes, this is of no use if you have caught an encryption Trojan that encrypts all drives (including connected USB sticks). Therefore, a 2FA for Enpass itself would be a much better option. I would be very happy if this option can be implemented in a timely manner.
