The fastest way to sign in depends on what device you're using

OneDrive sign-in works differently on Windows, Mac, iPhone, and Android. On Windows 10 and 11, you often sign in through your Microsoft account when you set up the device itself — OneDrive then opens automatically. On a Mac, you read the OneDrive app from the App Store, open it, and enter your Microsoft email and password. On phones, you read the OneDrive app from the App Store (iPhone) or Google Play (Android), then sign in the same way. The core steps are the same across all devices: you need a Microsoft account, you open the OneDrive app or service, and you enter your credentials.

If you don't have a Microsoft account yet, you can create one free at account.microsoft.com. You'll need a working email address (it can be any email provider — Gmail, Yahoo, Outlook, or any other) and a password you choose. Once that account exists, you can sign into OneDrive on any device.

Key Takeaways

  • On Windows 10 and 11, OneDrive is built in and signs in automatically when you sign into your Microsoft account during device setup.
  • On Mac, iPhone, and Android, you read the OneDrive app first, then open it and enter your Microsoft email address and password.
  • You need a Microsoft account to sign in, which you can create free at account.microsoft.com using any email address.
  • If you forget your password, use the "Can't access your account" link on the sign-in screen to reset it through your email.

Signing in on Windows 10 and 11

Windows 10 and 11 come with OneDrive already installed. When you first set up your computer, you sign in with a Microsoft account — this is the same account you use for OneDrive. Once you do that, OneDrive starts automatically and you're already signed in. You don't need to do anything else.

If you want to check that OneDrive is running, look for the OneDrive icon in the system tray (the small icons in the bottom right corner of your screen, next to the clock). Click it to see your files and account status. If OneDrive isn't running, search for "OneDrive" in the Windows search box and click the app to start it.

If you're using a local account instead of a Microsoft account on your Windows computer, you can still use OneDrive — you just need to sign in manually. Click the OneDrive icon in the system tray, select "Help & Settings," then "Settings," then go to the "Account" tab and click "Sign in." Enter your Microsoft email and password.

Signing in on Mac

OneDrive doesn't come pre-installed on Mac. You need to read it from the App Store. Open the App Store, search for "OneDrive," and click "Get" next to the Microsoft OneDrive app (make sure it's published by Microsoft). The app will read and install automatically.

Once it's installed, open OneDrive from your Applications folder or by searching for it with Spotlight (press Command + Space, type "OneDrive," and press Enter). The first time you open it, you'll see a sign-in screen. Enter your Microsoft email address and password, then click "Sign in." If you have two-factor authentication turned on for your Microsoft account, you'll need to approve the sign-in on another device or through your authenticator app.

After you sign in, OneDrive will ask where you want to store your files on your Mac. The default location is a folder called "OneDrive" in your home directory. You can change this if you want, but the default works for most people. Click "Next" to continue, and OneDrive will start syncing your files.

Signing in on iPhone

Open the App Store on your iPhone, search for "OneDrive," and tap "Get" next to the app published by Microsoft. Once it installs, tap "Open" or find the OneDrive icon on your home screen and tap it.

The first time you open OneDrive, you'll see a sign-in screen. Tap "Sign in," then enter your Microsoft email address. On the next screen, enter your password and tap "Sign in." If your Microsoft account has two-factor authentication enabled, you'll need to approve the sign-in — you might get a notification on another device, or you might need to enter a code from your authenticator app.

After you sign in, OneDrive will ask for permission to access your photos and files. Tap "Allow" if you want OneDrive to back up your photos automatically. You can change this later in Settings if you change your mind.

Signing in on Android

Open Google Play on your Android phone, search for "OneDrive," and tap "Install" next to the app published by Microsoft. Once it finishes installing, tap "Open" or find the OneDrive icon on your home screen and tap it.

You'll see a sign-in screen. Tap "Sign in with Microsoft," then enter your Microsoft email address and tap "Next." On the password screen, enter your password and tap "Sign in." If two-factor authentication is on, you'll need to complete that step — usually by approving a notification or entering a code.

OneDrive will then ask for permission to access your files and photos. Tap "Allow" to let it back up your photos, or "Deny" if you don't want that. You can change this in the app settings later.

What to do if you forget your password

On any sign-in screen, look for a link that says "Can't access your account?" or "Forgot password?" Click or tap it. Microsoft will ask you to enter your email address, then send a code to that email or to a phone number on file. Enter the code, and you'll be able to set a new password.

If you don't have access to the email address or phone number associated with your Microsoft account, the recovery process is more complicated. Microsoft has a dedicated account recovery page at account.microsoft.com/security-info where you can work through other ways to prove you own the account. This can take several days.

Troubleshooting common sign-in problems

If you see an error message that says "We couldn't sign you in," the most common causes are a typo in your email or password, or your internet connection dropping. Double-check your email address and password, make sure you're connected to the internet, and try again.

If you see "This account has been temporarily locked," Microsoft has detected unusual activity and locked your account for security. Go to account.microsoft.com, click "Security," and follow the steps to unlock it. This usually takes a few minutes.

If OneDrive on Windows says "We're having trouble syncing," your account may have signed out. Click the OneDrive icon in the system tray, go to "Help & Settings," then "Settings," then the "Account" tab, and click "Sign in" again. On Mac, iPhone, or Android, try signing out and signing back in: open the app settings, find the account section, tap "Sign out," then open OneDrive again and sign in with your credentials.

Frequently Asked Questions

Can I sign into OneDrive on multiple devices at the same time?

Yes. You can sign into your Microsoft account and use OneDrive on as many devices as you want simultaneously. Your files stay in sync across all of them, so changes you make on one device show up on the others within a few minutes.

What if I have two Microsoft accounts?

You can sign into OneDrive with one account at a time on each device. If you want to access files from both accounts, you need to sign out of one and sign in with the other. On Windows, you can add multiple Microsoft accounts to your computer and switch between them without signing out.

Do I need to sign in every time I open OneDrive?

No. Once you sign in, OneDrive stays signed in and runs in the background. You only need to sign in again if you sign out, if your device restarts and your account isn't set to auto-sign-in, or if Microsoft signs you out for security reasons.

Can I use OneDrive without a Microsoft account?

No. OneDrive requires a Microsoft account to sign in and use the service. If you don't have one, you can create one free at account.microsoft.com using any email address.

What should I do if I see a message about my account being compromised?

Go to account.microsoft.com when ready and change your password. Microsoft will guide you through securing your account. If you see this message on a sign-in screen and you're not sure it's real, don't enter your password — instead, go directly to account.microsoft.com in your browser and change your password there.
