Sentence: The user should not be able to change his password 2 times in a row.

[Sureshvemuri]

Is this correct to say - The user should not be able to change his password 2 times in a row.

(After any user created his password, only after 1 hour time elapsed the user can change the password)

2. Is it correct to say "This (zzz) is the existing password."

(previous password 1 - abc
(previous password 2 - bbc
current password - zzz

[Mister Micawber]

OK, or:

The user should not be able to change his password 2 times in a row.
The user should not be able to change his/her password twice within one hour.

This (zzz) is the existing password.
This (zzz) is your current password.
