Sign in to Mattermost
You’ll receive link to access Mattermost from your Mattermost System Admin or through an email invitation. Once you have your organization’s Mattermost link, navigate to that URL in a web browser, the Desktop App, or the Mobile App, then enter your user credentials.
Tip
We recommend bookmarking the Mattermost URL in your browser of choice so signing in to Mattermost is easy in the future.
Can’t find your Mattermost link? Ask your company’s IT department or your Mattermost System Admin for your organization’s Mattermost Site URL. It’ll look something like
https://example.com/company/mattermost
,mattermost.yourcompanydomain.com
, orchat.yourcompanydomain.com
. These URLs could also end in.net
.Mattermost Cloud customers can reach Cloud workspaces from the [Cloud Workspace Connection](https://customers.mattermost.com/cloud/connect-workspace) page by specifying their company or domain name.
After signing in, the team that appears first on your team sidebar will open. If you have not joined a team, the Team Selection page opens where you can view a list of teams that you can join.
