Mastodon ‘Approval Required’ Sign Up: How Long to Wait

When you sign up for a Mastodon instance and see the message “Approval Required,” your registration is not immediate. This happens because many instances use manual review to prevent spam and ensure new members fit the community. The delay can range from a few hours to several days, depending on the instance’s moderation team. This article explains why approval is needed, how long it typically takes, and what to do if you are waiting longer than expected.

Why Mastodon Instances Require Approval for New Sign Ups

Mastodon is a decentralized social network made up of independent instances. Each instance is run by its own admin or team. Unlike large platforms like Twitter, Mastodon instances often have small moderation teams. They manually review new sign-ups to keep out bots, spammers, and trolls. This is especially common on smaller or topic-specific instances where community quality matters more than quantity.

When you submit a registration form, the instance stores your username, email, and reason for joining. The admin or moderator team receives a notification. They then decide to approve or reject your application. The approval process is not automated in most cases. Some instances use tools like email verification or CAPTCHA before the manual step, but the final gate is human review.

Who Checks Your Registration

The instance admin or a team of moderators reviews each application. On single-admin instances, the same person who runs the server checks all requests. On larger instances, a moderation team shares the workload. The review includes reading your self-introduction or reason for joining, checking your email domain against known spam sources, and verifying you are not a duplicate account.

Why Some Instances Use Open Registration

Not all Mastodon instances require approval. Many use open registration, meaning anyone can create an account immediately. Instance admins choose between open and approval-based registration based on their moderation capacity and community goals. Approval-based registration is more common on instances with strict rules about content, language, or culture.

How Long Approval Typically Takes and What Affects It

The wait time for Mastodon registration approval varies widely. Most instances approve new accounts within 2 to 48 hours. Some process requests in under an hour if the admin is active. Others may take up to 7 days, especially if the admin is busy or the instance is very small.

1. Check the instance homepage for a stated wait time
   Many instance admins post an expected approval window on their about page or registration page. Look for text like “Approval may take up to 24 hours” or “We review requests daily.” This gives you a realistic expectation.
2. Look at the instance admin’s activity
   Visit the admin’s Mastodon profile if it is linked on the instance page. If the admin has not posted in weeks, approval may be delayed. Active admins usually respond faster.
3. Consider time zones and weekends
   Admins are volunteers. If you register late Friday night, your request may sit until Monday. Approval times often reflect the admin’s local working hours.
4. Check your email spam folder
   Some instances send a confirmation email after approval. If you do not see it in your inbox, check spam. Also ensure you entered your email correctly.
5. Resubmit only after one week
   If you have not heard back after 7 days, consider submitting a new registration. First, try to contact the admin through the instance contact page or their public profile. Resubmitting earlier may create duplicate requests that slow down the process.

What to Do If Your Mastodon Registration Is Stuck or Denied

Sometimes approval never comes, or you receive a rejection. Understanding why helps you decide your next step.

“Approval Required” Message Stays for More Than a Week

If your registration status has not changed after 7 days, the admin may be inactive or overwhelmed. First, check the instance’s public timeline or about page for any notice about delays. If you find none, try to message the admin from another Mastodon account or via email if listed. If the instance is unresponsive, consider choosing a different instance.

Registration Rejected Without Explanation

Some instances reject applications silently. Common reasons include a suspicious email domain, a generic reason for joining like “I want to use Mastodon,” or a username that looks like a bot. If your application is rejected, you cannot reapply with the same email on that instance. You must choose another instance or contact the admin to appeal.

Instance Is Defunct or Admin Has Left

Some Mastodon instances become inactive. The server may still be online, but no one reviews new registrations. In this case, your request will never be approved. Look for signs of activity: recent posts on the local timeline, a working status page, or admin posts within the last month. If the instance is dead, move on to a live one.

Open Registration vs Approval Required: Which Instance to Choose

Item	Open Registration	Approval Required
Description	Anyone can create an account instantly without waiting	Admin reviews each application before granting access
Typical wait time	Immediate	2 hours to 7 days
Best for	Users who want quick access or are trying Mastodon for the first time	Users who prefer a curated, spam-free community
Risk	Higher chance of spam or low-quality content	Possible rejection or long wait if admin is inactive
How to find	Check joinmastodon.org or instances.social for instances marked “Open”	Look for instances that say “Approval required” on the sign-up page

If you need an account immediately, choose an instance with open registration. If you value community quality and are willing to wait, approval-based instances are a good choice. You can also create a temporary account on an open instance while waiting for approval on your preferred instance. Use the Preferences > Account > Move from a different account feature to migrate followers later.
