Problem
You want to use Microsoft Teams but are not sure how to log in on desktop, mobile, or through a web browser. Some users accidentally sign in with the wrong Microsoft account, use an old Teams link, or get confused between personal, work, and school accounts.
Logging in correctly is important because your chats, meetings, teams, calendar, and files are connected to the account you use.
Solution
Use the official Microsoft Teams app or Teams website, then sign in with the correct Microsoft account. If you use Teams for work or school, sign in with your organisation email address. If you use Teams personally, sign in with your personal Microsoft account.
Step by step instructions
Log in to Microsoft Teams on the web
Open your web browser.
Go to:
Enter your Microsoft account email address.
This may be:
- Your work email address
- Your school email address
- Your Outlook.com email address
- Your Hotmail.com email address
- Another Microsoft account
Select Next.
Enter your password.
Complete any multi-factor authentication prompt if required.
After signing in, Teams will open in your browser.
Log in to the Microsoft Teams desktop app
If you do not already have Teams installed, download it from the official Microsoft page:
Install the app and open Microsoft Teams.
Enter your email address.
Select Next.
Enter your password.
Complete any verification steps if prompted.
Teams will open using the account you selected.
If you are using a work or school account, your organisation may require extra security checks before allowing access.
Log in to Microsoft Teams on iPhone or Android
Install the Microsoft Teams app from your device app store.
Open the Teams app.
Tap Sign in.
Enter your Microsoft account email address.
Enter your password.
Approve any verification request if your account uses multi-factor authentication.
Once signed in, Teams will load your chats, meetings, teams, and notifications.
Choose the correct account if you have more than one
Many users have more than one Microsoft account.
For example, you may have:
- A work Microsoft 365 account
- A school Microsoft 365 account
- A personal Outlook or Hotmail account
- A guest account in another organisation
If you sign in with the wrong account, you may not see the expected teams, chats, meetings, or files.
Check your profile picture or initials in the top corner of Teams to confirm which account is active.
Switch accounts in Microsoft Teams
Open Teams.
Select your profile picture or initials.
Look for an option to switch account or organisation.
Choose the correct account from the list.
If the account is not shown, select Add account if available and sign in again.
If Teams keeps opening the wrong account, sign out fully and sign back in with the correct email address.
Log in as a guest user
If another organisation invited you as a guest, use the same email address that received the invitation.
Open the invitation email and follow the Teams link.
Sign in with the invited account.
After signing in, use the organisation switcher in Teams to move between your own organisation and the guest organisation.
If the guest organisation does not appear, ask the team owner to confirm they invited the correct email address.
Use Teams if the desktop app will not open
If the Teams desktop app is not working, use the web version temporarily.
Go to:
Sign in with the same account.
This gives access to many core Teams features while you fix or reinstall the desktop app.
Sign out of Microsoft Teams
Open Teams.
Select your profile picture or initials.
Choose Sign out.
Close Teams completely if you are on a shared or public device.
Signing out is especially important if you have used Teams on a computer that does not belong to you.
Optional methods or tools
- Use https://teams.microsoft.com if the desktop app is not installed
- Download the desktop app from https://www.microsoft.com/microsoft-teams/download-app
- Use a password manager to store your Microsoft account password securely
- Use a private browser window when signing in on a shared computer
- Ask your IT administrator for help if your work or school account requires extra verification
Best practices or tips
- Always sign in with the account that received the meeting invite or team access
- Keep your recovery details and multi-factor authentication methods up to date
- Avoid using personal accounts for work or school Teams access unless instructed
- Sign out after using Teams on shared computers
- Keep the Teams app updated on desktop and mobile
Logging in to Microsoft Teams is straightforward when you use the correct account and the official Teams website or app. Most login confusion happens when users have several Microsoft accounts and accidentally choose the wrong one.
Using https://teams.microsoft.com is a reliable way to access Teams from a browser, while the desktop and mobile apps provide the best day to day experience. Once signed in with the correct account, Microsoft Teams will show your chats, meetings, files, calendar, and teams based on your permissions.
