Today I came across a post which explains all the different ways you can secure you all important Google account. The post describes three different ways, not including the two-factor authentication method which is now the most popular. Apparently, Google can use your fingerprint to secure your account.
With the highest number of online accounts, google is now the target of choice for hackers. So it only makes sense to further secure your online account. It might turn out to be a little inconvenient, but at the end of the day, it will be the account holders that are going to benefit the most from this.
