Powershell random password generator update#
PowerShell can then be used to update a group of mailbox passwords. The script is available at the Technet Gallery. If you need to set unique, complex passwords for multiple mailboxes, you can easily generate unique random passwords in Excel, and export them to a CSV file. Meaning that just running the command New-SWRandomPassword will generate a new password of a length of 8 characters containing both lowercase, uppercase, numeric and non-alphanumeric characters. This script enables you to generate a set of random complex passwords for a list of users which is imported as a CSV file. The parameters have the following default values: I also use the class to randomize randomization making the password a little more secure. Each generated password will contain atleast one char from each string (as long as PasswordLength => number of strings). Count specifies how many passwords to generate and -InputStrings specifies a list of strings defining which chars to use for password generation. The function was created to generate fairly randomized short string to be included in some test files back in history. The functions can be run in two ways, either using the parameter -PasswordLength to set a fixed password length or using the parameters -MinPasswordLength and -MaxPasswordLength to use a random length.īoth ways takes the parameters -Count and -InputStrings. Why Get-Random stops sampling after 62 chars I dont know, but I guess it is dependent on the string length. I wrote a function to generate a number of random passwords that will be complex enough for Active Directory.

This method will work good enough as long as there is a manual check that the password generated fulfills the requirements of the organization but when automating password generation for example when doing automated provisioning it just isn’t enough so I wrote a PowerShell function to generate random and complex passwords described in Method 3. This is a bit closer to passing the AD requirements, at least now we can be sure to get chars from at least two types, alpha numeric and non-alphanumeric, but on rare occasions it will not fulfill the requirement of chars from at least three of five categories. They are totally random and pretty hard to remember. It does what its supposed to but its not great if you are generating password for human beings.

In the example above it will generate a password with 8 characters containing at least 2 non-alphanumeric characters. It generated you a random password based on a character set defined within the code. I had one of the requirement to write Strong Random Password Generator :Microsoft Powershell earlier but it was completely command line based, and the applications users who were using it, due to non-technical background were not able to execute it correctly, So the team who requested the script wanted it in GUI form (Graphical user Interface. This method takes two parameters, length and minimum number of non-alphanumeric characters. NET class by calling the method GeneratePassword like this: The problem with this approach is that we can not guarantee that the password will be accepted by AD as complex enough since it could return a password containing only lowercase letters a-z. Using the operator -join will join the array back to a string with an empty string between each element. It’s quite easy to pipe a bunch of chars to Get-Random to get a somewhat random password like this:
This is my thoughts and three methods for generating passwords, the first two quite simple and straightforward and the third method a little bit more complex and definitely the one I recommend.
When provisioning new users to Active Directory we need to provide a new password and of course we want to generate a random password. $password.UPDATE : I’ve updated the script on Technet Gallery: ĭrastically improved performance and randomization logic. $randomIndex = get-random -Minimum 0 -Maximum $typeChoice.Count $randomIndex = get-random -Minimum 0 -Maximum $unt If = (33.47) + (58.64) + (91.95) + (123.126)}) Let’s generate a strong random password using the following PowerShell commands: Import System.Web assembly Add-Type -AssemblyName System.Web Generate random password ::GeneratePassword(8,2) The GeneratePassword method allows to generate a password up to 128 characters. $pwOptionList = New-Object -TypeName = 65.90}) Write-Warning 'Password is less than 10 Chars long' I'm fully aware that there are several of those out there, so there's nothing new under the sun, what I did add though, was the option to return the passwords in either clear text, as a secure string or in b64 format.Īny suggestions to improvement is always welcome. I often need to create random passwords on the fly, and I always have a PowerShell prompt open, so since I had some time on my hand, I decided to write a small password generator.
