Joining Meeting with Different Email than Registration

Hello, I have scheduled a large Zoom meeting for work that requires registration. If someone clicks to Join the meeting from the confirmation email, but is logged in from a different Zoom account OR not logged in at all, will they have an issue accessing the meeting?

I used the Zoom web portal to schedule the meeting. In the In Meeting Settings, I am not requiring authentication (because I am manually approving registrants). Also, the "Show a 'Join from your browser'" link is enabled. Are there any other settings I should consider?

Thank you!
