--     passphrase = 3,

local ok, err = password.check('newpass', nil, { min = "disabled,24,11,9,8", match = 3 })

if ok then
    print("success", "new password is fine")
else
    print("error", err)
end

-- You don't need to supply old pass as nil, so the above is same as:

local ok, err = password.check('newpass', { min = "disabled,24,11,9,8", match = 3 })

if ok then
    print("success", "new password is fine")
else
    print("error", err)
end

-- If you need to run more tests with same settings, you can use:

local quality = password.new{ min = "disabled,24,11,9,8", match = 3 }
local ok, err = quality:check("This!Is2Awesom3!", "IUsedToUse7his")

if ok then
    print("success", "new password is fine")
else
    print("error", err)
end
