> One login works on as many phones, tablets and computers as you like, all signed in at once.

There's no limit. Sign in with the same email and password on your phone, a tablet and a computer, and they all stay signed in at the same time. Each one shows the same jobs, diary, clients and paperwork, because they all read the same account.

## Getting it on another device

- **iPhone or iPad:** [Install the Mucka app on iPhone](/help/mobile/install-the-mucka-app-on-iphone)
- **Android phone or tablet:** [Install the Mucka app on Android](/help/mobile/install-the-mucka-app-on-android)
- **A computer:** open [app.mucka.ai](https://app.mucka.ai) in any browser

Then sign in with the email and password you already use.

## Lost a phone, or signed in somewhere you shouldn't be

Go to [**Settings → You → Security**](/settings/you/security) and tap **Sign out everywhere else**. Every other phone and computer signed in as you is signed out, and the one you're holding stays in. If you think someone knows your password, [change it](/help/settings/change-your-password) as well.

## Giving someone else their own login

Each person on your team should have their own login rather than sharing yours, so Mucka knows whose diary is whose and what each person is allowed to see. Invite them from [**Settings → Team → People**](/settings/team/team).
