Team profiles do not have an associated username or password, so you cannot sign directly into a team account. To access a team account, you'll need to be a Team Owner and use your drop-down avatar menu to 'Use Dribbble as' your team.
You can 'Use Dribbble as' your team to like, message, or leave Feedback under the team name or post shots with a single attribution.
If you no longer remember the Team Owner for your Team, please contact our support team.
