How do I register?

  • Updated 9 October 2026
  • Author Katarzyna Banaś
  • Category Registration and login

1. Choose a network

When you open the app, on the “Where you want to login?” screen choose:

  • Company – type the name of your company or university and choose it from the list,
  • Public – if your company doesn’t use inOneCar. Tap “Continue”.

Then tap “Create an account”.

2. Fill in the form

Enter your first name, surname, email address and password (at least 6 characters), tick the required consents and tap “Register”. You don’t need a phone number – the app will ask for it when you make your first booking.

3. Confirm your email address

You’ll get an email with an activation link. Click it – only then can you log in. The link opens in your browser. The activation link doesn’t work?

Who can join a company network?

Each company decides who has access. You can see the rules in the form under “See who can access …”. Usually it’s one of three methods:

  • Company email address – registration only works with an address in the company’s domain. The app rejects other addresses and shows the allowed domains.
  • Administrator approval – after you register, your account waits until a person appointed by the company approves it. You’ll get an email when that happens.
  • Company login (SSO) – you don’t create an account in the app. Just log in with the “Log in via … SSO” button using your company credentials. How to log in?

Some companies also ask for additional details, such as an employee number.

The public network

If you choose Public and enter an email address in the domain of a company that uses inOneCar, you’ll end up in that company’s network. To create a public account, use a private email address.
