Digital Identity Means Security
One particular leaf of that nettle is authentication, and here I think we Brits can have some optimism. NCSC is working with the government and the FIDO Alliance on improving the adoption of “passkeys” across the public and private sectors. If you are not familiar with passkeys (which are already widely used), imagine you want to sign in to your Google Account on a new device. Instead of entering a password, a passkey allows you to log in to your account with a device you’ve already verified (e.g., your phone). You don’t need to remember a password and no-one else can log in as you because they don’t have your phone.
