Tesco is reissuing Clubcards to some members after the supermarket chain uncovered a security issue with some members’ accounts.

More specifically, Tesco said that it believed a database of stolen information was being used to try and gain access to Clubcard members’ accounts. The stolen usernames and passwords were from other platforms and tried on Tesco’s websites — and the stolen information was successful in some cases.

The supermarket chain confirmed that no financial data was accessed from its systems, and it has not been hacked. Tesco said that it was reaching out to the some 600,000 members whose Clubcard accounts may have been affected, issuing them new cards.

One TPG U.K. staffer received the email from Tesco, which read:

“We recently became aware of some fraudulent activity on your Clubcard account, which included an attempt to access your Clubcard vouchers. We picked this up quickly and, to be on the safe side, blocked your account immediately.

This means that, when you next try to sign in, you’ll be asked to reset your password. As an extra precaution, we will reissue you with a new Clubcard number.

What happens now?

  • All your Clubcard vouchers and points will be transferred to your new Clubcarrd number — rest assured you won’t lose out on any value.
  • You will be able to access your Clubcard vouchers again via your Clubcard account within 5 working days.
  • You can continue to collect points online straightaway.”

Tesco Clubcards are one of the best ways to rack up points and miles quickly. The premise of the programme is that when you spend with Tesco, you’ll earn Clubcard points. Once you’ve spent enough with Tesco and your Clubcard, you can turn those points into vouchers. The vouchers can be used to save money in store, online and when filling up with petrol.

Once you have enough vouchers, you can redeem them for everything from travel to restaurants, magazine subscriptions and everything in between. For example, you can cash in £2.50 of your vouchers for 600 British Airways Avios — worth nearly £7 based on TPG U.K.’s most recent valuations. Or, with Virgin’s Flying Club, £2.50 worth of Tesco Clubcard vouchers can be exchanged for 625 Virgin Atlantic Flying Club miles — worth £8 based on TPG U.K.’s most recent valuations.

This incident is a great reminder of using different passwords for each account you may have. That way, if a database gains access to one of your passwords, it’ll be different for other accounts. Airline and hotel loyalty programmes are no stranger to hacks, either.

According to the BBC, about 19 million people have a Clubcard account.
