Easy to share
Use a phrase on a business card, in a conversation or in an approved contact notice.
PhraseID
A memorable way to reach your Hat.
Choose a phrase people can remember and type instead of sharing a long Hat code. PhraseID gives professional contacts a simpler route into your private channel.
No phone number or email required for core Hat use.
The useful difference
A clearer way to handle sensitive work.
Attached to your Hat
Register and manage a PhraseID for the applicable Hat in the app.
Availability checked
The app checks phrase availability and the naming rules. Limits depend on the plan.
How it works
Three deliberate steps.
Choose your Hat
Open the PhraseID control for the Hat you want people to reach.
Claim an available phrase
Follow the displayed length, word and availability rules.
Share and verify
Give contacts the phrase. Independently verify the person behind it for sensitive work.
Know the boundary
Choose controls with clear expectations.
A memorable alias is a lookup route, not proof of a person’s legal identity. Phrase lookup and registry data have a different boundary from encrypted conversation content.

Where can I use PhraseID?
Open City of Hats to review the controls available for your client, content and plan. The app shows applicable requirements before you proceed.
What should I check before sharing sensitive information?
Verify the recipient, use a supported device and choose appropriate access and retention rules. Review the Security Evidence Center for boundaries and evidence status.
City of Hats is free to use. Feature availability and limits vary by plan and client. Premium is optional; review current limits in the app or on the plans page.
