In this article we will show you how to generate random password using Powershell
We will use the GeneratePassword method of the System.Web.Security.Membership class.
Syntax
Public Shared Function GeneratePassword (length As Integer, numberOfNonAlphanumericCharacters As Integer) As String
Parameters
length
The number of characters in the generated password. The length must be between 1 and 128 characters.
numberOfNonAlphanumericCharacters
The minimum number of non-alphanumeric characters (such as @, #, !, %, &, and so on) in the generated password.
Examples
Lets see some examples of this
The first is 8 characters in length with 3 non-alphanumeric characters I need.
Add-Type -AssemblyName System.Web [System.Web.Security.Membership]::GeneratePassword(8,3)
This is the output that I saw
powershell password
In this example we will generate a 16 characters in length with 8 alphanumeric characters as well
Add-Type -AssemblyName System.Web [System.Web.Security.Membership]::GeneratePassword(16,8)
This will generate 10 passwords of 16 characters in length with 8 alphanumeric characters as well
Add-Type -AssemblyName System.Web
1..10 | % { [System.Web.Security.Membership]::GeneratePassword(16,8) }
I saw these generated
_sy.p1-.m+RW_d_{
_hN.mc}_Q-E}_n_9
nY1.6(!&iw&%e}_v

{&h.Gd!4EP-X_8_-
Qfz(=X.$$MBu*^$j
_4_.0={iQ.e+CQ_j
/@D.if;_Hp]qK}_O
If you want to create a file with all of the generated password you can use the following
Add-Type -AssemblyName System.Web
1..10 | % { [System.Web.Security.Membership]::GeneratePassword(16,8) } | Out-File .\Passwords.txt
