Account Security FAQ

Yev Yev

Backblaze takes your account security very seriously. We provide multiple account authentication options including Two-Factor Verification (2FV) via Short Message Service (SMS) and Time-based one-Time Passwords (ToTP), as well as an Single Sign-on (SSO) option.

When creating your Backblaze account you must create an account using email and password credentials or link to one of your other accounts via SSO. Once an account is created you can change your Sign In preferences at any time, and can change your email and password whenever you deem necessary as well.

Note* - some Groups may restrict member ability to do change login credentials.

Email & Password

If you choose to create an account using an Email and Password or are changing one of these in the future, please keep in mind that your password must be deemed secure by our backend systems. We use a number of methods to determine whether a password is secure, including checking its length (it must be at least 8 characters long), searching public databases of commonly used and compromised passwords, and other methods that evolve as we seek to keep our users’ accounts secure.

If you choose to sign in with your Email and Password, we strongly suggest you turn on 2FV via SMS or ToTP.


If you choose SSO, that provider and your settings with them will handle your Backblaze login process. This means that when you arrive to you will put in the email address associated with your SSO account, and then you will be taken to your SSO-providers login screen. You will need to follow any prompts and pass the security methods they require, and once done you will be brought back to the Backblaze website in a signed-in state.

If you have already created a Backblaze account with Email and Password credentials and would like to enable SSO, you can do so by following the instructions here: Enabling SSO for Individuals.


We strive to keep your account safe and if we deem your password is not safe we will flag it as such and require you to change it. If you are having issues logging in or have been locked out of your account, please check your email for more information. If you are still experiencing issues, please reach out to support.
