How to Manage a Tumblr Blog with a Team: Group Blogs, Admins and Members

How do you give a team access to a Tumblr blog without sharing a password? #

With a group blog. According to Tumblr's Help Center (read 3 October 2026), group blogs are blogs with multiple members. Only secondary blogs can be group blogs and only primary blogs can be members, so every person joins with their own Tumblr account. Tumblr's Protecting Your Account page says not to share your passwords, and membership makes sharing unnecessary.

Adding people is a job for a web browser, because the apps cannot send invites. The roles are two: admin and member. This guide is about Tumblr blogs on the desktop web unless an app is named.

What can admins and members do on a group blog? #

Tumblr Communities have roles of their own (admins, moderators and members), and only primary blogs can take part, so Communities are a separate feature from group blogs.

How do you set up a group blog step by step? #

1. Create or choose a secondary blog. On the web, click Account, then + New. If you do not see the option to add members, the Help Center says the blog might be a primary blog.
2. In a web browser, click Account in the left sidebar of the dashboard, then click the blog.
3. Click Members in the right sidebar.
4. Type the email address the person uses for their Tumblr account, or their primary blog URL, and click Invite to this blog.
5. Tumblr emails an invite link that works once. You can also send the link yourself, and it is valid only for the username you entered.
6. To make someone an admin, open the Members page and click Promote to admin next to their name. Read the next section first.
7. Optional. Under Blog settings and Blog avatar, switch on Show author portraits so each post shows its author's avatar. Tumblr advises checking that members are comfortable with this before you do.

Who should be admin, and how does off-boarding work? #

Handing a sideblog to a new owner follows the pattern the Help Center gives for moving a sideblog to a new account: invite the new account, make it an admin, and leave if you wish. The Help Center adds that importing content from one blog to a different blog is not possible.

Export before any change. On the web, choose Settings, select the blog and use Export. The Help Center says exports are web-only, each blog is exported separately, backups are kept for 3 days and Tumblr allows 4 exports per blog per month. For a group blog, only admins are told when the export finishes. Deleting a primary blog deletes the whole account, and the Help Center says data is kept for 30 days, so treat that as the last step, not a clean-up.

Which security habits apply to every account on the team? #

• Own login for each person. Tumblr says staff will never ask for your password.
• Two-factor authentication everywhere. It adds an authenticator-app code to the password. Download the backup codes, store them safely, and remember that each works once.
• A password manager, not the browser. Tumblr strongly recommends a password manager and says not to save passwords in a web browser.
• A reachable email. Losing access to the registered address means losing the account, and changing it needs the current password. A verified email is also needed for messaging, two-factor authentication and comments.
• Reviewed connected apps. Some apps request read and write access; revoke any you do not trust from the apps settings.
• Account activity emails. They cannot be turned off, so point them at a mailbox someone actually reads.

What if a client wants to own the blog, or access goes wrong? #

The habits of ownership, least access and regular audits are covered, for ad accounts, in how agencies manage client ad accounts. For logging in to several owner accounts on one computer, see Tumblr browser profiles; for the rules, see the Tumblr rules guide.

Where ADSSPEED fits #

Each team member should sign in with their own Tumblr account. ADSSPEED helps the person who runs several of them on one computer. It is a desktop app for Windows and macOS that manages many browser profiles; each profile keeps its own cookies, local data and browser settings, so accounts you own or are authorised to manage can stay signed in side by side. Profiles can be opened, stopped and organised in bulk, and profile data stays on your own computer. ADSSPEED is not affiliated with Tumblr.
