password-generate

Password generators.

Based on actual use cases encountered in the wild.

• mixed: (alpha) + (num) + (symbol)
• alphanum: some systems don't allow symbols
• num: primarily those intended for phone usage

Notes

Symbol

Only using the underscore _.

Some don't allow fancier symbols, but the underscore seems accepted everywhere.

Alpha

Assuming both uppercase and lowercase allowed.

The only contrary case I have seen is banks, which uses case-insensitive passwords - but then it doesn't disallow inputting both upper- and lower- case either.

Num

Ever-present.

I haven't seen a system that disallow numeric inputs yet.

First character

Is always an alpha.

Systems have various rules disallowing what is or is not allowed, but the alpha seems accepted everywhere.
