For security reasons, PSCouchDB does not use CouchDB token cookies. But authentication can be stored inside the current powershell session. By default, credential storage is allowed so that the Authorization parameter can only be specified once.

To modify the saved credential preference, set this:

$CouchDBSaveCredentialPreference = $false   # default is $true

Set a cookie:

$password = "password" | ConvertTo-SecureString -AsPlainText -Force
Set-CouchDBSession -UserId admin -Password $password
Set-CouchDBSession -UserId admin    # prompt password

Get a session:

Get-CouchDBSession          # PSCredential
Get-CouchDBSession -Clear   # string format user:password

Now let verify a protected read database without Authorization param:

Get-CouchDBDatabase -Database test

And remove a session:
