Yes! When you sign in for the first time on My Vodafone you’ll need your mobile phone to receive a verification code. You will also need to set up a unique password that meets certain security levels. Try using a combination of characters, numbers and upper/lower case letters when setting it up.
Bill pay customers also need their self-service PIN to access confidential information such as your latest bill. Remember, this code is different to your password. It's made up of the last four digits of your customer number.
