Issue: How to enable two-factor authentication on Gmail?

Could you explain to me how to turn on two-factor authentication on Gmail account?

Solved Answer

Two-factor authentication, also known as 2FA,[1] TFA or two-step verification, is one of the methods to add more security to your personal information online. Once you set it up, you have to enter your login, password, and verification code that is being sent to your mobile device or authentication app in order to access your account.

You can enable two-factor authentication on Gmail, Facebook, Twitter, Reddit and many other online services. Users are advised[2] to turn on this feature as prevention of data breaches and other unauthorized access to your account if some evil-minded people guess your password.

If someone gets access to your account,[3] they might send emails on behalf of you, steal your contact list or get access to your other accounts. For instance, criminals might reset your banking account password. There's no doubt that this may lead to serious problems.

Therefore, two-factor authentication gives an extra layer to cyber security. Google allows enabling this feature on all its services, including Gmail, Drive, G+, YouTube, and others. Though, it’s impossible to set 2FA for Gmail only. You will need to protect all Google account.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
