When you first login, you are asked to set up a four digit PIN that you choose to make sure only you can use your debit cards, credit cards and PayPal to pay for fuel from your car. For security purposes, your four digit PIN is required every time you use BPme. Your safety and privacy is our number one priority. Please make sure you keep any passwords and PINs secure and not to write your details down. If you would like to use fingerprint authentication instead of a PIN, please be aware that any fingerprint authentication on your mobile will be valid and you are responsible for any purchases made using any fingerprint stored on your smartphone.
