You may not keep security information or top-secret plans on your Tumblr account, but that doesn't mean it's not worth securing from potential password hacks. Here's a quick guide on setting up two-factor authentication to protect your Tumblr gifsets, memes, songs, blogs, and more.

How to set up Tumblr's two-factor authentication

After logging into Tumblr, setting up two-factor security is as simple as visiting the settings page. Here's what you need to do.

  1. Click the user icon in the upper-right corner of the Tumblr website.
  2. Click Settings.

  2. Enter you account password.

  1. Click Enable.
  2. Click the switch next to either Send code via SMS or Generate code via authenticator app. For better security, choose to generate a code in an authenticator app like Google Authenticator or Authy, or a password manager that supports that functionality like 1Password.

If you choose to use SMS (which is a much less secure method of two-step authentication), follow the steps above through Step 5, when you click Enable. After that, do the following:

  1. Click the switch next to Send code via SMS.
  2. Enter your phone number.

Additionally, because Tumblr uses the Google Authenticator service for two-factor authentication, this means that you can use an app like Authy instead of an SMS message to authenticate your account. You can set that up by toggling the Generate code via authenticator app option.

This gives you a QR code you can scan with the Google Authenticator or Authy apps; from there, you can generate random approval codes whether that device is connected to the internet or not.
