Two-factor authentication (also called 2FA) adds an extra layer of security to your Zapier account by requiring access to your phone or mobile device, in addition to your password. Only using a password to protect your account is still susceptible to security threats because it only represents a single piece of information someone needs to acquire.
By using 2FA, anyone who wanted to access your account would need both your password and an access code generated on your phone or mobile device. This means that even if someone stole your password, they would be unable to access your account without your mobile device.
We highly recommend you to enable two-factor authentication on your Zapier account.
If you want to share Zapier with other people on your team, it's recommended to use Zapier for Teams. By being members of the same team, you'll be able to continue sharing access to Zaps by using shared folders while still enabling two-factor authentication for each team member.
