What are the disadvantages of 2FA?
Cons of two-factor authentication
- Time-consuming. Time may be an absolute metric, but it’s also relative.
- Cost. Like time, cost is relative.
- Failure can be disruptive. 2FA creates two distinct hurdles an attacker would have to jump through to gain access.
- It’s not absolutely secure. No security is infallible.
