Microsoft 365 Login and Sign-In Help

Updated 2026-08-19 · 989 words

Open {site}, select Sign In, and use the Microsoft account connected to the Microsoft 365 services you need.

What is the official Microsoft 365 login page?

The verified login page for Microsoft 365 is reached through Microsoft’s official site. Open {site} rather than using a sign-in link from an unexpected email, text message, advertisement, or pop-up.

Before entering account information, inspect the address bar. The connection should be secure, the address should use a Microsoft-owned domain, and the company name should be spelled correctly. A padlock only means the connection is encrypted; it does not prove that the page belongs to Microsoft.

If the address looks unusual, contains misspellings, or places another company’s name before or after “Microsoft,” close the page. Start again from the verified site. Never provide a password or verification code to a person claiming to be support.

How do I sign in to Microsoft 365?

To sign in to Microsoft 365, have the email address or username for the account ready. You may also need a password, an authenticator approval, a security key, or a verification code.

  1. Go to the verified Microsoft 365 sign-in page and select Sign In.
  2. Enter the email address, phone number, or username associated with the Microsoft account.
  3. Select Next. If Microsoft asks which account type to use, choose the personal account or work or school account that holds the services you need.
  4. Enter the password on the Microsoft sign-in screen.
  5. Complete any requested authentication. Authentication is the step Microsoft uses to confirm that the person signing in controls the account.
  6. After sign-in, choose the Microsoft 365 service you want to open.

If a shared or public device asks whether you want to remain signed in, decline. Sign out when finished and close every browser window. Do not save the password in a browser you do not control.

Which Microsoft account should I choose?

Microsoft may show more than one account when an email address or device has been used for different Microsoft services. Choosing the correct account determines which files, settings, and organization resources appear.

  • Personal Microsoft account: An account an individual created for personal Microsoft services. Select this option when the Microsoft 365 access belongs to you rather than an employer or school.
  • Work account: An account created or managed by an employer. The organization’s administrator may control passwords, verification methods, and access rules.
  • School account: An account created or managed by a school. Access may depend on the school’s policies and the account’s current status.

If the wrong account opens, sign out, close the browser, and start again. A private browsing window can help prevent a saved account from being selected automatically. On a managed work or school device, contact the organization’s administrator before removing accounts or changing device settings.

What should I do if I forgot my Microsoft 365 password?

Use the “Forgot password?” or similar recovery option shown on the official Microsoft sign-in screen. The correct recovery path depends on whether the account is personal or managed by a workplace or school.

  1. Enter the account email address on the Microsoft sign-in screen.
  2. Select the password-reset or account-recovery option.
  3. Complete the identity checks Microsoft presents. Available methods depend on the security information already connected to the account.
  4. Create a new, unique password if Microsoft confirms the recovery request.
  5. Sign in again and update the saved password on devices or apps that still use the old one.

For a work or school account, the organization may require an administrator to reset the password or restore access. If you cannot use any recovery method shown, follow Microsoft’s official account-recovery prompts. Do not repeatedly guess passwords, because repeated failed attempts can trigger additional security checks.

How do I fix common Microsoft 365 login problems?

Most Microsoft 365 sign-in problems involve the wrong account, outdated saved credentials, a missing verification step, browser data, or an organization’s access policy.

  • Incorrect email address or password: Check spelling, capitalization, keyboard language, and accidental spaces. Confirm that you selected the correct personal, work, or school account.
  • Repeated sign-in prompts: Sign out of Microsoft accounts in the browser, close it, and try again. If the prompt continues, use a private browsing window or clear Microsoft-related cookies for the affected browser.
  • Verification code never arrives: Confirm that the masked phone number or email shown belongs to you. Check filtered email folders, wait for the current attempt to finish, and avoid requesting many codes in quick succession. Use another verification method if Microsoft offers one.
  • Verification code is rejected: Enter only the newest code and make sure it is for the current sign-in attempt. Codes from earlier attempts may no longer work.
  • Browser page will not load: Refresh the page, disable extensions that block scripts or cookies, or try a current version of another browser. Switching between Wi-Fi and cellular data can help identify a connection problem.
  • Account is locked: Follow the identity-verification or recovery instructions displayed by Microsoft. Do not trust anyone who asks for the password or verification code to unlock the account.
  • Administrator-managed access is denied: Contact the workplace or school administrator. Only that organization can explain its access rules, restore a disabled managed account, or change required verification settings.

How do I contact Microsoft 365 support?

Reach Microsoft 365 support through the verified Microsoft site and select the support, help, or contact option. Sign in when possible so Microsoft can identify the account and display the support choices available for that account type.

Before contacting support, prepare the account email address, whether it is personal or organization-managed, the exact error message, the device and browser being used, and the steps already tried. For a work or school account, also have the organization’s name and administrator contact available.

Do not send support your password, one-time verification code, recovery code, or authenticator approval. Verified support may ask you to confirm account details through a secure Microsoft process, but a support representative should not need those secrets.
