### Modifying Tenant Authentication Settings

This example shows how to modify tenant authentication settings.

```
$plainpassword = "Password1234plain"
$securepassword = $plainpassword | ConvertTo-SecureString -AsPlainText -Force
Set-VBOTenantAuthenticationSettings -EnableAuthentication -CertificateFilePath "C:\cert.pfx" -CertificatePassword $securepassword
```

Perform the following steps:

1. Assign your certificate password to the `$plainpassword` variable.
2. Run the [`ConvertTo-SecureString`](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.security/convertto-securestring) cmdlet with the `$plainpassword` variable to turn the password into the `SecureString` type. Save the result to the `$securepassword` variable.
3. Run the `Set-VBOTenantAuthenticationSettings` cmdlet with the `$securepassword` variable and `EnableAuthentication` parameter.
