The passphrase is an extra security feature that you can enable on your Payfast Dashboard to make your security signature (sent when a payment is made) more secure.
You may set your passphrase as a combination of up to 32 characters of your choosing.
To enable the passphrase on your account, do the following:
- Log in to your Payfast account.
- Navigate to Settings > Developer settings.
- Enter your Security Passphrase and click Save. Please note: Your passphrase cannot be more than 32 characters.
Once you have set your passphrase: you will need to enter it into your plugin's integration settings along with your Merchant ID and Key. It's important to check if your plugin/integration supports this feature before you set it up.
