Two-factor authentication (2FA) makes logging onto web services much more secure but it can also be a pain in the neck as it adds an extra step to the sign in process. Usually this involves typing in verification codes that you have to retrieve from an app on your phone. Google is attempting to simplify 2FA with a new feature for its online services called Google Prompt. Here's what you need to know.

Google runs a 2FA system that usually requires a six-digit code that you can get by SMS or an authenticator app. It can be a bit annoying for users to get on their phone, open the relevant app and then key in the code. For some, that's enough to deter them from using 2FA. But Google Prompt solves this problem by making 2FA a one-touch process.
Prompt replaces the code with a simple push notification that comes through your phone. When you type in your username and password on any Google service, you will receive a notification on your mobile device and all you have to do is tap "Yes" to sign in.
Google Prompt is compatible with Android and iOS phones. With the latter, the iPhone has to be at least a 5S. You can switch on Prompt on your Google accounts by going to the Security section.
