It is now completely unavailable.
The fact remains that this feature was a security risk as it would record people's passwords -- either a "quite close but not close enough" password, or a password they use somewhere else -- in plaintext. If this information was exfiltrated due to a vulnerability in an unrelated piece of software it could seriously compromise the security of that user.
I thought about making it available if the username didn't match, but this was equally problematic since some folks either mistyped their username, or tried a number of possible usernames with their "usual" passwords (a terrible security practice but, well, humans are humans).
I don't have a good solution for your use case. Technically, I could do something about it, but it would be borderline unusable. I could let you provide a GPG public key to encrypt this information, so that you can only decrypt it with a private key on your own computer. The problem is that a. this requires the gnupg PHP extension which is almost never available on commercial hosting and b. the setup and use of such a feature is well beyond what most people can or are willing to do.
If you are interested in something like that, please let me know. I might be able to come up with a custom plugin for you.
