I’ve been asked to synchronise or re-calibrate Mobile PINsentry with Online Banking. Is this a genuine request?

No. This is most likely a fraudulent attempt to gain access to your account and you should report it immediately. We’ll never ask you to synchronise or re-calibrate Mobile PINsentry or email you asking you to enter details to synchronise it.

To report suspected online fraud, call us on 0345 600 2323* (outside the UK, +44 247 684 2063). Lines open 24 hours a day, 7 days a week.

If you're suspicious about an email that claims to be from us, forward it to internetsecurity@barclays.co.uk then delete it. There's no need to call us unless you believe you've disclosed your personal details or been a victim of fraud.
