Google has updated its Chrome browser so that it can automatically and securely enter saved passwords and credit card information into forms, the company has announced. The browser now uses biometric authentication like a fingerprint to automatically fill in credit card details without having to ask for your three-digit CVC each time. In a new dialog box, you can choose from a list of saved account credentials without having to tap individual form fields to log into a website.
Both functions not only offer convenience, but are also intended to increase the security of transactions on the web. Biometric security makes it difficult for someone to shop online when they have access to your device. You still need to enter your CVC when you set up a credit card for the first time. You can then authenticate with security like a fingerprint.
Using Chrome to store and enter passwords also has its own security advantages over simply trying to enter them from memory (using a dedicated password manager is another option). For example, passwords for any site or service can be more complex and unique (which makes guessing difficult) because you don’t need to remember them and, unlike a human, the software cannot easily be tricked into entering fake phishing- Sites, says Google.
Chrome’s new credit card auto-fill feature builds on the support of WebAuthn, a biometric authentication standard. This is the same technology that Google used last year to get users to sign in to some of its services without the need for a password.
According to Google, the new function for automatically filling out credit cards is already available on Windows and Mac. Both features, including the auto-populate dialog box, will be available on Chrome for Android in the coming weeks.
