Airtable supports two-factor authentication (also known as 2FA or two-step authentication) for greater account security.
Two-factor authentication adds a second level of authentication to your Airtable account login. So, in addition to your email/username and password, you (or anyone trying to log into your account) will need to have some extra information or a physical device of yours. By choosing a second authentication factor, you can protect user logins from remote attacks that may exploit stolen credentials.
Note that you can only set up two-factor authentication with Airtable if you create an account using an Airtable password and email—if you log in with a Google account, you can't set up two-factor authentication this way (but you can set up two-factor authentication on your own Google account).
To enable two-factor authentication on your Airtable account, go to your account page at https://airtable.com/account. You can also access your account page by clicking on your user icon in the top right corner of the screen, then clicking the "Account" option from the dropdown menu.
Once on the account page, click on the "Two step auth" link next to your user icon:
You'll then be asked to confirm whether or not you want to enable two-factor authentication—click the blue "Enable" button.
Then, you'll need to set up your phone by adding a phone number which you can use to receive authentication codes.
You'll need to enter your phone number (including the country code).
You should then shortly receive a phone call or text at your designated phone number providing you with your authentication code. After entering the correct code, you'll then be brought to the 2FA configuration page. You now have 2FA enabled on your Airtable account. Congrats!
You can add a second authenticator app step if you'd like by clicking on "Add another second step" and "Use an authenticator app."
There should be two options available: "Use an authenticator app," and "Call/Text my phone."
Clicking "Use an authenticator app" will generate a QR code that will allow you to configure an authenticator app on your phone.
After configuring the authenticator app and entering the verification code, using the authenticator app will be set as your default second step. (You'll be able to tell because it'll have a bold "(default)" after it.) You can change which of your second steps is your default second step by clicking the "set as default" option.
In case you lose your phone, there are some backup options for you to recover your account.
Under the Backup options section of the 2FA page, there's a section that says "Show single-use backup codes." Clicking this will reveal a list of 12-character backup codes. In the event that you lose your phone or cannot receive or generate authentication codes, each of these codes can be used only once to access your account. Make sure you write these down or copy them into a safe place so that you can access them without getting into your account.
If you are afraid that your list of backup codes has been compromised, you can regenerate the backup codes by clicking the "regenerate" option here.
The "Add an additional backup option" will let you list a phone number (separate from the phone number you used for your second step) for recovery. For example, you could use the phone number of a trusted partner or a separate business phone in case you lose access to your primary phone number.
If you decide that you'd like to disable two-step authentication, simply click on the "(disable)" option under the header.
You'll be asked to confirm that you want to disable 2FA one more time before it'll be officially disabled. You can re-enable it again at any time by following the steps in the previous section.
