Gmail is one of Google’s most popular products and one of the largest email services available worldwide. To set up an account, individuals simply need to select a unique username and choose a password that meets Google’s security requirements. After that, Gmail credentials can be used for logging in to the web application, as well as for linking a Gmail account to mobile phones or other devices.
Security should always be a concern when it comes to online accounts, because even the most complex passwords are still vulnerable to hacking and other digital attacks. In order to combat against these risks, Google offers its Gmail users the option to enable an additional level of security. This is commonly known in the online world as two-factor authentication, although Google’s documentation refers to it as 2-Step Verification.
The concept of 2-Step Verification is simple: when a user tries to log in to a new Gmail session, they are required to enter their standard password and then also confirm a unique security code that is sent to their mobile phone. By matching the security code from the phone, Google can validate the identify of the individual logging in to the site. This way, even if a hacker manages to obtain a user’s Gmail password, they will not be able to infiltrate the account.
In addition to the mobile phone option, Google also allows Gmail 2-Step Verification to be used with a physical device known as a security key. It is a small USB stick that contains a unique code linked to the owner’s Gmail account. When the USB stick is plugged in to a computer, Gmail verifies the owner’s identity and allows them to continue with the log in process. Note that at this time, the physical security key option is only supported through the Google Chrome web browser.
Statistics indicate that out of Gmail’s more than one billion users, only a small percentage have enabled 2-Step Verification on their account. This is likely because two-factor authentication methods are seen as complicated to set up and inconvenient to maintain. To make things easier, Gmail allows users to update their 2-Step Verification settings on the go. For example, if a user logs in to Gmail in Chrome from a personal home laptop, the website will allow for 2-Step Verification to be disabled on that specific machine. This will let the user log in quicker in the future while still maintaining security from outside threats.
Of course, no online security system is ever perfect. Gmail’s 2-Step Verification can still be vulnerable if a hacker manages to steal your mobile device or finds a way to reroute your text messages. If you notice any suspicious activity within your Gmail account, it is best to change your password immediately and contact Google support for help.
