2FA apparently has unlimited tries

I entered a wrong code 6 or 7 times (for science!) and then entered the right one, which still worked.
And with a 6-digit code, there are “only” 1,000,000 possibilities, which isn’t that much.
(and on average you’re in after 500,000 tries)
Having a limited amount of tries (3 is probably more than enough, maybe just even 1) would be nice.

The codes need to be voided after a few minutes, in my opinion. Maybe after 5 minutes from sending the email, the old code is voided?

Edit: A timeout penalty for incorrect pin code attempts would also work well.

Something like an authenticator app would also work (Eg. Microsoft two-factor app, or Google authenticator).

Google authenticator would be a nice way to handle this.

They already are. From the e-mail I received yesterday:

“This code will expire in 15 minutes.”

For future use, I think it would be great if 2FA was built into the Roblox app for mobile devices (See example below):

Attempts to input a code aren’t unlimited. You should try doing say, 100, and see what happens.

What’s the actual limit?
Anything higher than 5 seems way too much.
