Hello @pmassey,
I’m sorry for the late response.
Even if you have the link and password for a Zoom video recording, you may still be required to sign in and register to access the playback. Zoom may prompt you to authenticate your account by signing in with Zoom or by verifying your email and entering a security code before you can view the recording.
If you see a message asking for permission or registration, follow the on-screen instructions to sign in or verify your email. This extra step is sometimes required for added security, even if you already have the link and password.
