The Mail app on is the built-in all-in-one email client for macOS. You can use it to set up all your emails — personal and work — on your Desktop, so you don’t have to check out your email providers’ websites every time you get an email. It works well with Gmail, Yahoo, Outlook, and most other email services that we know of. All you need to do is to set them up on the Mail app!

One of the great things about the Mail app is its minimalistic style. It doesn’t have those fancy and complicated features like with other third-party email apps, and its user interface is so easy to use. Just click on the message that you want to read, refresh the app to get new emails, then click Compose to send out an email. In terms of design and functionality, the Mail app is both basic and practical.

Setting up an email account on Mail is so easy. Just follow the steps below:

  1. Open the Mail app by clicking its icon from the Dock. You can also launch it from Finder > Go > Applications > Mail.
  2. Click on the email provider you want to use. You can choose iCloud, Exchange, Google, Yahoo, AOL, and even social media accounts, such as Facebook, LinkedIn, Flickr, Vimeo, and Twitter. If you’re using an email account with a different domain, click Other Mail Account.
  3. Hit Continue, then enter the email address and password for your new account.
  4. Tick off the apps you want this email to be associated with.
  5. Click Done, and you’re all set up!

If you need to add multiple email accounts, just repeat the process until you see all of them in the Mail app. The app will automatically download all your emails from these accounts, and the duration of the process depends on how much data there is to download.

But what happens if you changed the password to your email account and you need to update the Mail app? It happens. Maybe you were prompted to change your email password for security purposes or you simply forgot and had to reset it. Either way, you need to change the password in the Mail app, so that you can keep sending and receiving emails on your Desktop.

Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

How to Change an Email Account Password in the Mail App

There are two ways you can change your email account password using the Mail app in Mojave. The first method is by changing the password in the Preferences section of the app. The second method is to remove the email account, then add it back using the new login details.

Before updating your password, it may be helpful to perform some basic maintenance like removing junk files to prevent potential issues. Outbyte macAries aims to help with this task, but make sure the software fits your system cleanup needs.

Method #1: Change Password via Mail App Preferences

The first method to change the password in the Mail app requires editing some entries in the app settings. The process is pretty straightforward and the app will be updated with the new password once completed.

To do this, follow these instructions:

  1. Click the Mail icon from the Dock to launch the app.
  2. From the top menu, click Mail.
  3. Choose Preferences from the drop down menu.
  4. Click on the Accounts tab, then choose the email account you want to edit.
  5. Click on the email account, then select the Server Settings tab. You should see the username and password for both the Incoming Mail Server and Outgoing Mail Server.
  6. Click on the Password field, delete the existing password, then type in the new one. Make sure you enter the correct password to avoid errors during the verification process.
  7. Click on the General tab and save your changes.

The Mail app should now be updated with your new password and you should see new emails coming in if there are any.

However, sometimes users still get a password error even though they’ve entered the correct password in the settings. If you get this error, do the following steps:

  1. Click on the Settings icon from the Dock, then choose Internet Accounts.
  2. Choose the email showing the password error, then click Mail Account.
  3. Type in your new password, then click Sign in.

Your email account should now be updated!

Method #2: Remove Then Re-Add the Email Account

If the first method doesn’t work and you’re still getting a password error, the other option is to delete the email account you want to update, then add it back again using the new login credentials.

Before you delete your account, make sure you have a backup of all your important emails to avoid data loss.

To remove your email account from the Mail app:

  1. Open the Mail app, then click Mail from the top menu.
  2. Click on Preferences, then choose the account you want to delete.
  3. Click the (-) button at the bottom to delete that email account.

However, if the email account you want to remove is being used by other apps on your Mac or if it is connected to your iCloud account, you will be asked to remove it from Internet Accounts instead. To proceed:

  1. Click the Internet Accounts button on the popup message.
  2. Uncheck Mail if you only want to delete the email account from the Mail app.
  3. Click the Remove button if you want to stop using that email in all of your apps.

After deleting your email account following the steps above, you can add it back in the Mail app as a new account. Make sure to type in the new password correctly to avoid login issues.


The Mail app makes it easy for Mac users to access all of their emails in one place. This app is a huge help, especially for those with multiple email accounts from different email providers. If you need to change the password for your email accounts, you can try the first method first because it is less of a hassle. If it doesn’t work, jump to the second method. Once you’ve updated your login details, you’ll be able to send and receive emails from the Mail app once again.
