Randomly generate a "more reliable" user name? Do you have any ideas?

The project has a need for a random number of user names, passwords, mailboxes or something. Everything else doesn't matter, that's it. usernameOur boss is not satisfied with the look.
I am a random 12-character number, uppercase and lowercase letters. Like what cfgzBHKRV367
Lying trough, he said it's best to encapsulate a method that randomly generates a 比较靠谱's user name. I really don't know how this can be counted. What do you guys think?

There are no such third-party libraries (PHP), or everyone give me a thought, I write it myself.

Prepare a library of English words and then randomly assemble them so that you can at least identify the words that make sense.
Further, the thesaurus can be categorized, such as with an adjective + a rank.

You go to Heroku and try a new project.
