One Device, Many Identities: Keep Your Communities Separate
You can now create multiple identities on a single device and assign each one to a different guild. Work stays work, personal stays personal — and no one can link them.
On most platforms, your account is you. One username, one profile, attached to every community you’re in. Your coworker in the company Slack can find you on the gaming server. Your ex can see you in the hobby group. Everything is linked because the platform decided you only get one identity.
Eris already lets you own your identity as a cryptographic keypair instead of a platform account. But up until now, you still only had one. If you joined five guilds, all five saw the same you.
That changes today.
Multiple identities, one device
You can now generate as many identities as you want from the Identities section in Settings. Each one gets its own keypair, its own display name, and its own fingerprint. They’re completely independent — there’s no hidden link between them, no shared username, no way for a server admin to discover that two identities belong to the same person.
Create one called “Work” and another called “Personal.” Or go further — “Gaming,” “Art Community,” “Anonymous.” Label them however you like.
Pick an identity when you join a guild
When you join a new guild, Eris asks which identity you want to use. If you only have one, it skips the question entirely — the feature stays out of your way until you actually need it. But if you’ve got multiple identities, you’ll see a picker with all of them listed.
You can also create a brand new identity right there in the join flow if none of your existing ones feel right.
Once you’ve joined, that guild is bound to the identity you picked. Every time you open that guild, Eris automatically switches to the right identity. You don’t have to think about it.
Why this matters
Compartmentalization without multiple accounts
On Discord, keeping your work life separate from your personal life means running two accounts. Logging out and back in. Managing two email addresses. It’s a hassle, and most people just don’t bother — which means their boss can find their anime server.
With Eris, you get real separation with zero friction. Different display names, different cryptographic fingerprints, different identities. All on one device, switching automatically as you move between guilds.
Actual privacy, not just display name changes
This isn’t a “nickname per server” feature. Each identity has its own Ed25519 keypair. From a cryptographic standpoint, they’re completely different people. A server admin looking at two of your identities would have no way to mathematically prove they belong to the same device.
That’s a much stronger privacy guarantee than anything you get from a centralized platform, where the company always knows which accounts belong to the same person — even if they let you use different nicknames.
You’re still in control
All your identities live on your device. Eris doesn’t upload them to a central server, doesn’t create accounts, doesn’t ask for your email. You can delete an identity whenever you want (as long as it’s not assigned to any guilds). Your last identity can’t be deleted — the system makes sure you always have at least one.
Managing identities in Settings
The Identities section in Settings shows all your identities at a glance:
- Display name and optional label
- Fingerprint (the
eris:prefix you might recognize from the federation system) - Guild count — how many guilds are using this identity
- Active badge — which identity is currently in use
You can edit labels, update display names, and remove unused identities. It works the same way on both the web client and the Flutter mobile app.
The bigger picture
We talked about portable identity before — the idea that your identity is a cryptographic key you own, not an account some company controls. Multi-identity takes that further. You don’t just own an identity. You own as many as you need, each one purpose-built for a specific part of your life.
It’s the kind of feature that doesn’t exist on centralized platforms because they want to link everything to one account. That’s how they build profiles, serve ads, and enforce bans across communities. Eris doesn’t do any of that, so there’s no reason to limit you.
Try it out — open Settings, create a second identity, and join a guild with it. You might be surprised how good it feels to keep things separate.
