What is rezStream Protection?
To improve security, rezStream Cloud uses Multi-Factor Authentication which will occasionally prompt you to verify the device you are working on and send you an email with a verification code when you sign in.
This helps protect your account and data if your username and password are compromised, guessed, or exposed.

We understand that having to check your email every time you sign in would be cumbersome, so we have built this in such a way that with regular usage you should rarely see this screen.
You should expect to see it in the following cases:
- You are using a new device (phone, tablet, computer, etc.) to sign into rezStream Cloud.
- You are using a new browser to sign into rezStream Cloud.
- It has been more than a month since you used your current device or browser to sign into rezStream Cloud.
- You have recently cleared the cookies in your browser.
What is Multi-Factor Authentication (MFA)?
Multi-Factor Authentication (MFA) is a widely used security method that requires you to provide two or more verification "factors" to access an application. The different factors include:
- Something you know - typically your username and password
- Something you have - like your phone or a verification code that only you can get via your email or an app that you control that generates these codes
- Something you are - like a fingerprint, voice, or facial recognition
A user that can provide two (or more) of these factors when signing in dramatically reduces the chances that a hacker can access their account because while that hacker may get access to one factor (like a password), it is much more difficult for them to compromise the additional factors.
How does rezStream Cloud use MFA?
rezStream Cloud requires MFA via a verification email when you sign in from an unrecognized device — meaning a browser on a computer, phone, or tablet that you have never used before or haven't used in over a month. Once you verify your identity, we securely store a token in your browser so that your device is recognized the next time you sign in.
So even if someone obtains your username and password, they still cannot sign in — because they would be accessing your account from an unrecognized device, which triggers the MFA verification step.
CAUTION: If you are re-using the same password for both rezStream Cloud and your email (or any other applications), we strongly suggest you change all those re-used passwords immediately. It is strongly recommended that you have a unique password for every app you use to improve the effectiveness of MFA. You might want to consider using a "Password Manager" application to generate and securely store (and in most cases, auto-fill) these unique passwords.
What if I can't find the email with the code?While we do our best to ensure reliable delivery, verification emails can occasionally land in your spam or junk folder. If it's not there, the email may have failed to send — click the Resend Code button (labeled Send New Code) beneath the countdown timer to request a new one.
If you still cannot locate the verification email, please contact our support team. They can verify your identity and help restore your access.
What if I can no longer access the email address on my account?You will have to contact our support team if you no longer have access to your account's email address. They will be able to help you update your email address and regain access.
Why do I have to enter an authentication code every time I log in?
Please refer to our troubleshooting guide if you are prompted for authentication codes every time you log in.
