Most people use the same password everywhere and if your password is compromised anyone can login from anywhere – what [**2FA/OTP**](http://admin.exchangedefender.com/) service enables you to do is use your cell phone as a secondary ID check. [![](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2018/10/OTP-Authentication-I1.png)](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2018/10/OTP-Authentication-I1.png) **When you login to ExchangeDefender, the system will immediately text you a 4 digit PIN to your cell phone. This way even if someone were to guess or steal your password, they will not be able to login without having access to your cell phone as well.** As we blogged about implementing [advanced password security](http://www.exchangedefender.com/blog/2018/09/new-feature-encryption-enrollment-account-reset/)), plain text passwords are a thing of the past and the whole universe is moving towards having that additional layer of security to make sure unauthorized changes aren’t being made. > [![](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2018/10/OTP-Authentication2-1024x657.png)](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2018/10/OTP-Authentication2.png) This is why we are making ExchangeDefender 2FA/OTP free for ExchangeDefender Pro and it works at all three levels – Service Provider, Domain administrator (domain.com login) and individual end user accounts at [https://admin.exchangedefender.com](https://admin.exchangedefender.com). Once you’ve authenticated with a PIN on the top level you will not need to re-authenticate in order to manage and support your MSP clients or the end users so by all means enable it for everyone. We hope you enjoy this feature and start relying on it, don’t worry this is no bait and switch, we do not intend to start charging for it down the road – it’s all about improving security and keeping our clients protected. It’s just what we do!
