The wizard handles the rest
On first launch Nexview creates an administrator account with you and then asks about the services. Seven steps, five of which can be skipped — whatever is missing you add later in the settings.
Account and picture
Username, display name, e-mail address, password. The username cannot be changed later — it is the identifier you sign in with. The display name can; it is what others see in requests and approvals.
The address is not yet verified afterwards — not even for the first account. Nexview sends the confirmation as soon as a mail server is configured. That looks fussy but has a reason: an address taken on trust with a typo in it would only surface once it has locked you out.
The profile picture is the one step you can genuinely skip without a thought.
The TMDB key
TMDB supplies everything you see: titles, posters, descriptions, casts, dates. The key is free — create an account on themoviedb.org, generate a key under settings → API, done.
Without it Nexview runs in demo mode with invented titles. Enough to look around; not enough to request, because those titles do not exist.
The key is checked as you enter it — you find out at once whether it works, rather than noticing later from empty pages.
The public address
What address is Nexview reachable at? This ends up in every invitation and in every link inside a notification.
It is verified before you continue. That is deliberate: a wrong address otherwise surfaces only when the first invitation leads nowhere.
If Nexview runs behind a reverse proxy, this is the address your people type into their browser — not the container's.
A mail server belongs here
Without a mail server nobody can be invited, no password can be reset — and your own address stays unverified. That is the catch: signing in with a password requires a verified address. While you are still in the wizard's session you notice nothing; the next time you sign in you will.
You need server, port, encryption and the sender address. Here too the continue button only unlocks after a successful connection test.
For home use your own provider's address usually does.
With Plex you can do without. Connect a Plex server and you need no mail server: linking verifies your address along the way — the provider has already checked it. Everybody else then signs in with their own Plex account, and Nexview creates their accounts as they go. Invitations are not needed at all.
The order matters. Connect Plex before you sign out. With neither a mail server nor a Plex link, the next sign-in locks you out: signing in with a password requires a verified address, and without signing in you cannot reach the settings to connect Plex.
Radarr, Sonarr — and the rest later
The remaining steps ask for Radarr and Sonarr. Both can be skipped; Nexview then runs as a plain catalogue in which nothing can be requested.
How to connect them — and what tends to go wrong — is on the page connecting services. That also covers Plex and the notification services, which the wizard does not ask about at all.
