From sign-up to your first screen.

Four steps, about five minutes, no person on our side involved: ask for a phone, confirm your email, open the one-time link that shows your key, sign in and see the screen.

Checked on a live phone · 12 Oct 2026About 5 minutesNo card

Step 1 · Sign up

Open eriusphone.com/start, enter your email, choose Android and type your invite code.

Invite code. Sign-up is by invite during early access. No code yet? Ask for one with the early-access form on the home page.
Android or iPhone. Android gives you a working phone now. iPhone is a waitlist today: no phone is created, we write to you when that changes.
One phone per email. A second request with the same email does not create a second phone.

"Today's new phones are all taken." The number of new phones per day is limited. Your confirmation link stays valid for 24 hours, so try it again the next day.

Step 2 · Confirm

Confirm your email.

We send a confirmation link. It works once, for 24 hours.

Open the email with the subject "Confirm your email for ERIUS PHONE".
Press the button in it. A page opens with one more button, Confirm and set up my phone. Press that too.
A progress page appears and refreshes by itself: email confirmed, phone being set up, key link emailed.

The page says "about two minutes". In our test run on 12 October 2026 the phone was ready 43 seconds after the confirmation.

Why two buttons? Mail scanners open links in emails before you do. The link alone changes nothing, so a scanner cannot use up your confirmation.

Step 3 · Your key

Open the one-time link and save the key.

A second email arrives, "Your ERIUS PHONE device is ready". It has your phone id and a button, Get my API key.

The claim page with the button Show my API key — The claim page first shows a button, not the key.

Have a password manager or another safe place open.
Press Show my API key. The key is displayed once. It starts with sdk_.
Copy it and store it. Reloading the page does not show it again.

The claim page showing the API key once (masked in this picture) — The key is shown once. It is masked in this picture.

The key is the only credential. There is no password. Whoever has the key can use your phone, so treat it like one. If you lose it, see a lost key.

Step 4 · First screen

Sign in and see your phone.

Open the dashboard, paste the key, press Sign in. Your phone is on the Home page; Open live screen shows it.

The dashboard showing the live screen of a phone with navigation keys beside it — Your phone in the dashboard. Click to tap, drag to swipe.

The phone is new: no account is signed in and only the system apps, Firefox and Google Play are on it.

The same, from a terminal

Your agent uses the same key.

Set the three variables once, then ask the API who you are.
