To help protect your Tesco account, we send you an email when we notice unusual sign-in activity, like an attempt to sign in from a different device than normal. If you know this sign-in was you, you don’t need to do anything.
If you’re using incognito mode/private browsing, you could receive an email every time you sign into your account. This is because we can't identify the device you’re signing in from.
If you’re unsure, or know that you didn’t sign into your Tesco account, reset your password to protect your account. If you need further help, please call us on 0800 022 3087.
