Account Settings 

Full Name 

Full names appear in the Direct Messages member list and team management modal. By default, you will receive mention notifications when someone types your first name. Entering a full name is optional.

Username 

Usernames are unique identifiers appearing next to all posts. Pick something easy for teammates to recognize and recall. By default, you will receive mention notifications when someone types your username. In order to maintain message integrity, changing your username does not update @mentions in messages already posted. Username must begin with a letter, and contain between 3 to 22 lowercase characters made up of numbers, letters, and the symbols ‘.’, ‘-‘, and ‘_’.

Nickname 

Nicknames appear in the Direct Messages member list and team management modal. You will not receive mention notifications when someone types your nickname unless you add it to the Words That Trigger Mentions notifications list in Notifications.

Position 

Position can be used to describe your role or job title. It appears in the profile popup that shows up when you select a user’s name in the center channel or right-hand sidebar.

Email 

Email is used for signing in, notifications, and password reset. Email requires verification if changed. If you are signing in using a single sign-on service, the email field is not editable and you will receive email notifications to the email you used to sign up to your SSO service.

Profile Picture 

Profile pictures appear next to all posts and at the top of the channel sidebar next to your name. To change your profile picture, choose Select, then choose an image. For best results, choose an image that’s at least 128 x 128 pixels in size. Supported image formats include: BMP, JPG, JPEG, and PNG. The GIF file format is not supported.

Password 

You may change your password if you’ve logged in by email. If you are signing in using a single sign-on service, the password field is not editable, and you must access your SSO service’s account settings to update your password.

Multi-factor Authentication 

When this option is available, you can require a phone-based passcode in addition to your password when signing in.

To enable, download Google Authenticator from iTunes or Google Play for your phone, then:

1. Select the Add MFA to your account button.

2. Use Google Authenticator to scan the QR code that appears.

3. Enter the token generated by Google Authenticator, then select Save.

In future, you will be asked to enter a passcode from Google Authenticator in addition to your password on login.

If you are unable to scan the QR code, you can:

1. Select the Add MFA to your account button. You should see a Secret Key below the QR code.

2. Open Google Authenticator.

3. Select the + button, then select Manual Entry.

4. Enter an account name.

5. Enter the Secret Key from Mattermost into the Key field in Google Authenticator, then select Save.

6. In Mattermost, enter the token generated by Google Authenticator, then select Save.

Sign-in Method 

This option allows you to switch your sign-in method from email/password to a single sign-on option, and back again.

For example, if AD/LDAP single sign-on is enabled, users can select a “Switch to using AD/LDAP” button and the enter their AD/LDAP credentials to switch sign-in over to AD/LDAP. They also need to enter the password for their email account to verify their existing credentials. Following the change, users receive an email to confirm the action.

View Access History 

Access History displays a chronological list of the last 20 login and logout attempts, channel creations and deletions, account settings changes, or channel setting modifications made on your account. The details of the Session ID (unique identifier for each Mattermost browser session) and IP Address of the action is recorded for audit log purposes.

View and Logout of Active Sessions 

Sessions are created when you log in with your email and password to a new browser on a device. Sessions let you use Mattermost for up to 30 days without having to log in again. Select Logout on an active session if you want to revoke automatic login privileges for a specific browser or device. Select More Info to view details on browser and operating system.

Desktop Notifications 

Desktop notifications appear in the top corner of your main monitor when there is activity in Mattermost.

Email Notifications 

Email notifications are sent for mentions and direct messages after you’ve been offline for more than 60 seconds or away from Mattermost for more than five minutes. Change the email where notifications are sent in Account Settings > General > Email.

If your System Admin has enabled Email Batching, you’ll have additional options under this settings to select how often email notifications will be sent. All notifications received over this time period are combined and sent in a single email.

Mobile Push Notifications 

Push notifications can be sent to your mobile device if you have the Android or iOS app installed. You can choose the type of activity that will send a notification.

By default, push notifications are sent “For mentions and direct messages”. If push notifications are sent “Never”, the Mattermost setting to trigger push notifications depending on your Mattermost availability is hidden. If your System Admin has not set up push notifications, this setting will be disabled.

If you’re actively viewing a channel (Public or Private), Direct Message, or Group Message using the Desktop App or a browser, no push notifications will be sent for that channel. If a notification is viewed using the Desktop App or a browser, the lockscreen notification will clear on Android, and on iOS the badge on the Mattermost app icon will count down accordingly.

Trigger Mobile Push Notifications When 

You can also choose when to send push notifications depending on your Mattermost availability. By default, push notifications are sent if your availability is Away or Offline. If Send Mobile Push Notifications is set as Never, this setting is hidden. If your System Admin has not set up push notifications, this setting will be disabled.

Words That Trigger Mentions 

By default, you receive notifications when someone posts a message that contains your non-case sensitive username or @username. You also receive notifications when someone uses the @channel, @all, and @here mentions. You can customize the words that trigger mentions by typing them into the input box. This is useful if you want to be notified of all posts on a certain topic, for example, “marketing”.

Reply Notifications 

When Collapsed Reply Threads (Beta) is disabled, you can choose to receive mention notifications when someone replies to a thread you have started or have participated in.

• You are considered to start a thread when you post a message to which other members of your team reply.

• You are considered to participate in a thread when you post a message using the Reply button in an pre-existing thread.

Automatic Direct Message Replies 

Set an automated custom message that will be sent once per day in response to Direct Messages. Mentions in Public and Private Channels won’t trigger the automated reply. Enabling Automatic Replies sets your availability to Out of Office and disables desktop, email, and push notifications. This setting is experimental and must be enabled by your System Admin.

Theme 

Select Theme Colors to select from four standard themes designed by the Mattermost team. To make custom adjustments on the four standard theme colours, select a standard theme and then select Custom Theme to load the standard theme into the custom theme color selectors.

Select Custom Theme to customize your theme colors and share them with others by copying and pasting theme vectors into the input box. Observe a live preview as you customize theme colors, then select Save to confirm your changes. Discard your changes by selecting Cancel, or by exiting the settings modal and selecting Yes, Discard.

In Enterprise Edition, if you belong to multiple teams, you can optionally select the checkbox “Apply new theme to all my teams” to have the theme show up across teams. Otherwise, the changes will only apply to the current team.

Learn more about the custom theme color selectors here.

Select Import theme colors from Slack to import a Slack theme. In Slack, go to Preferences > Sidebar Theme and open the custom theme option. From there, copy the theme color vector and then paste it into the Input Slack Theme input box in Mattermost.

When messages in Mattermost include images, an image preview can display directly below the message for image attachments, image link previews, and in-line images over 100px in height. You can set this preference to Expanded or Collapsed.

Message Display 

Select the formatting for messages in the center channel. “Compact” mode decreases the spacing around posts, collapses link previews, and hides thumbnails so only file names are shown. Some formatting types, such as block quotes and headings, are also reduced in size.

Collapsed Reply Threads (Beta) 

Collapsed Reply Threads (Beta) offers an enhanced experience for users communicating in threads and replying to messages. Collapsed Reply Threads are available in Mattermost Cloud and from self-hosted Mattermost v5.37 as an early access beta, and are disabled by default. If your System Admin has enabled Collapsed Reply Threads for your workspace, you can enable them in your Mattermost instance to start being notified about threads you’re following in a new Threads option at the top of the channel sidebar.

Enable Join/Leave Messages 

This setting controls whether system messages about users joining or leaving a channel are visible. When On these messages will appear. When Off, these messages will be hidden. If any users are added to or removed from a channel, a system message will still be shown even if this setting is Off.
