How to Change Your Mastodon Handle (Step-by-Step Guide)
Guide to changing your Mastodon handle — your local @{handle} plus instance (e.g. mastodon.social) — rules, steps, and monitoring.
Why Change Your Mastodon Handle?
Your Mastodon handle is federated — @{handle}@instance. Change it to:
- Match your Bluesky handle for a unified fediverse identity
- Move to a shorter local handle before your instance fills up
- Rebrand after a project name change
- Claim a premium 1-2 char handle the moment it frees up on your instance
- Fix a handle with hyphens (not allowed — underscores only)
📋 Step-by-Step: How to Change Your Mastodon Handle
- 1
Pick your instance
Mastodon handles are per-instance. Choose your instance (e.g. mastodon.social) at joinmastodon.org/servers first.
- 2
Open Account Settings
Sign in to your instance, click Preferences → Account → Username.
- 3
Check availability
Enter 1-30 chars: letters, numbers, underscores (_). No hyphens. This checker verifies via mastodon.social.
- 4
Confirm
Save. Your @{new}@instance is live — old handle is released on that instance immediately.
Vérifiez si votre pseudonyme est disponible
Enter a username and get alerted the moment it becomes available on any platform.
⚠️ Important Things to Know
🌐 Per-instance
A handle on mastodon.social doesn't block the same handle on another instance — each instance is separate.
✏️ Local part only
This checker verifies the local part before @instance. Full user@domain is out of scope.
🔤 Lowercase
Mastodon handles are stored lowercase.
🔗 Old handle released
On that instance, your old @{handle} is freed immediately.
