Cant Sign Into Microsoft Account On Mac Or Pc

Some users report that doing this indeed fixes the “We can't sign into your account” issue, however, a great portion of those who tried it also say it’s bogus. If you couldn’t access your Microsoft account even after multiple reboots, it’s time to move onto more sophisticated solutions.

All Microsoft products and services are connected to your Microsoft account. Even Windows offers the option to login using the

same account. That said, many users have multiple Microsoft accounts to separate their personal life from professional. Others like to use a local account instead. But, how do you change the Microsoft account on your Windows 10 computer when needed? How do you create/add a new account?

While a Microsoft account is not necessary to use Windows 10 computer, it is recommended nonetheless. There could be other reasons to update or change your Microsoft account details on your computer:

  • You bought a second-hand computer and the last owner failed/forgot to format it.
  • You lead a dual life and have multiple jobs requiring you to sign in to different accounts.
  • You are an advanced user, enthusiast, or dev who loves tinkering around.
  • You want to use two OneDrive accounts to maximize free storage space it offers.

Let's find out how you can change Microsoft account on Windows 10 computer and what you need to keep in mind.

Add Email ID and Number to Same Microsoft Account

Many users wanted to change their Microsoft account's sign-in email and phone number. No need to create a new account just for that. You can add up to 10 email IDs and numbers to the same account as 'alias' without creating a new account for each one. You can also replace old account details with a new one or make the new ID 'primary'.

Step 1: Open your Microsoft Account manage area and under Account aliases where you can add a new email ID or number.

Step 2: Choose the first option if you want to create a new Outlook account right there and the second option if you are using a third-party email provider like Gmail.

You must know that there is no way to move aliases from one Microsoft account to another. You can't recover aliases either. If you delete an alias in one Microsoft account, it will be deleted from Microsoft servers forever, and you or anyone else can't use it on another Microsoft account.

Change Microsoft Account to Local and Vice Versa

Other users wanted to get rid of their Microsoft account and go local or vice versa.

For the uninitiated, there are two types of accounts you can create on Windows-powered computers. You can either create a local account or a Microsoft account. A local account is one that does just requires a username and password. Also, you can remove your password later. None of your Microsoft data leaves your computer or synced to another Windows device. It stays offline and on a single device. Several Microsoft apps like Store, Skype, etc. won't work or downloaded without a Microsoft account though.
On the other hand, a Microsoft account will sync all your activities across devices and keep all the data in the cloud on Microsoft's servers. The benefit is obvious. Do you want to change between them?

Step 1: Press Windows key+I to open Settings and click on Accounts.

Step 2: Click on 'Sign in with a local account instead' option to begin the process.

Follow on-screen instructions after that. You may have to enter your current Microsoft account's password/PIN for verification.

To change from a local account to a Microsoft account, you will follow the same steps. This time, you will select 'Sign in with a Microsoft account instead' option that should be visible because you are using a local account instead.

Change to New Microsoft Account or Add New Microsoft Account

You have a new Microsoft account with a different email ID ( or, which is owned by Microsoft) and want to use this new account on your Windows 10 computer.

Step 1: Open Settings again (Windows key+I) and go to Accounts > Family & other users.

Step 2: Click on 'Add someone else to this PC' button.

You will now follow on-screen instructions and enter the new Microsoft account ID and password to add that account to your computer. The setup instructions will include settings like 2FA and Windows Hello. Just like when you added your first Microsoft account.

What you are doing is creating a new user account on your computer with this new Microsoft account. You can switch between these two users like you normally do from the Start menu or reboot your computer.

Dual Accounting System

Microsoft allows a lot of ways to manage your Windows 10 computer. Unlike Windows 7 and earlier versions, you have more options like using a local or Microsoft account, opening up new possibilities. I suggest you take the time to think through what you want to do and how you want it done. That will save you the trouble of going back and forth between settings and accounts. Always protect your account with features like Hello or 2FA. Either will save you a lot of headaches someday.

How to check if you have a Microsoft account

If you’re using a computer that’s running Windows 10 as its operating system, you’ll need a Microsoft account to log in.

If you have an existing account with, Hotmail, Office 365, OneDrive, Skype, Xbox or Windows, good news — the email address and password that you use to access that account will also work as your Microsoft account. Simply input those same details to log in to Windows 10.

If you don’t have an account with any of the above services, then you don’t currently have a Microsoft account. You’ll need to set one up in order to log in to Windows 10. Follow the below steps to get going.

How to set up a Microsoft account

  1. First, go to and click on ‘Create one!’ to start the process.
  2. Fill in your first name and surname. The name that you use here will be displayed across all the Microsoft services you use and will be visible to friends, family, colleagues and other Microsoft users.
  3. Enter the email address you’d like, e.g. firstname_lastname and choose from the drop down list whether you’d like it to end with or Outlook will now check to see if that unique email address is available. If it’s already taken, it will suggest some available email addresses or you can try something different until you find an acceptable email address you’re happy with.
  4. Once you’ve chosen your email address, you need to set up a password. Microsoft requires your password to be at least 8 characters long with at least two out of lower and upper case letters, numbers and symbols. Your Microsoft account password is case sensitive, so make sure you take note of where you’ve used capital and lower case letters.
  5. Fill out your country/region, date of birth and gender.
  6. Now add either your telephone number, an alternative email address or both. If you have a problem with your Microsoft account, Outlook will use these contact details to verify your identity to protect your account.
  7. Finally, type in the random characters displayed at the bottom of the screen. There is an audio option if you prefer.
  8. Choose whether you want to opt in to promotional emails from Microsoft and then click on ‘Create account’ to finish setting up.
  9. Outlook will now create your email inbox. Select your preferred language and time zone. (The UK is in UTC+00:00) and click on save. You now have a Microsoft account.

How to link your computer to your Microsoft account

  1. Click on the Start button and then go to Settings > Accounts > Your account.
  2. Select ‘Sign in with a Microsoft account instead,’ input your Microsoft account password and click ‘next’. It might take the wizard a moment to prepare the set up, but when it’s ready, enter your Microsoft account email address and password, then click ‘next.’
  3. You may need to verify your identity with a confirmation code sent to the email address or phone number you provided earlier when you set up your Microsoft account, so have your phone or email account to hand. If they’re not available, select ‘I can’t do this right now’ and return to the set up wizard when you’re ready. Once you’ve inputted the code, click on ‘next.’
  4. Finally, click on ‘switch’ to finish the set up. Windows 10 will set up your new Microsoft account. This will not affect your files.

In summary


We've now completed the process of setting up a Microsoft account. The next time you sign in to Windows 10, use your Microsoft account name and password to log in.

Your Microsoft account will synchronise all the machines connected to that account, so look out for the changes next time you log in to a different device.
