Not only do you have to authenticate your account using a password, you also have to authorise all payments through your phone. Tide also requests a selfie every time you log onto a new device to make sure it’s actually you.
Tide’s bank accounts are provided by ClearBank, which means they are covered by the Financial Services Compensation Scheme (FSCS), which protects deposits of up to £85,000. Tide itself is not a bank, but it is regulated by the Financial Conduct Authority (FCA).
