Payflow is PayPal’s secure gateway that allows merchants to process online store payments with any major payment processor, bank or card association.

If you receive an "Authentication Error" message when attempting to collect funds for an authorized payment when using the Verisign (PayPal) Payflow Pro gateway, it may be due to the character length of the password you've chosen for your Payflow Pro account.

An easy solution is to reset your password within your Payflow Pro account. Be sure to follow PayPal's password guidelines for Payflow Pro.


Nobody likes to be stopped in their tracks by an error message. Hopefully just a quick password reset will get you back up and running in no time. If not, Volusion is here to help.
