That's the great thing, you don't have to! rezora now uses a One Time Password (OTP) system.
That means instead of having a set password, each time you go to sign in you will enter your username and then be sent an expiring one-time password. Check the email address attached to your account for that One Time Passcode, then use it to sign in.
The One Time Passcode email will be titled "rezora Verification Code" and will be sent from our info@rezora.com address.
