Set up once. Then it is four fields and a name.

This is a one-time setup, and it happens first because everything downstream runs on it. Point Persona Kit at your own Steel Browser — Steel Cloud with an API key, or a deployment you host yourself — and add the residential proxy account you already have. Credentials are encrypted with AES-256-GCM before they are stored.

• Steel Cloud or self-hosted Steel Browser
• Bright Data, IPRoyal, Smartproxy, or a custom gateway
• Keep several proxies and switch which one is the default
• Your traffic runs on infrastructure you control

Give your persona a name, pick a country and a state or province, and optionally a city. Persona Kit fills in the identity around it — a street address with a postal code that belongs to that area, a date of birth, a phone number, a username, and a device profile whose timezone and language match the location you chose.

• 20 countries with state and province granularity
• US personas support city-level addresses and real ZIP codes
• Generated address, date of birth, phone, and username
• Configurable browser, OS, and screen resolution

Assign the persona its own address on a Persona Kit domain and it will start receiving real mail — verification codes, receipts, whatever the accounts it signs up for send. You can also point a persona at an address you actually watch and have its mail forwarded there instead.

• A dedicated, working address per persona
• One combined view across every persona's inbox
• Optional forwarding to your real address
• No countdown on an address you're using
• Free keeps 7 days of history; Pro keeps it permanently

Launch the persona into a live browser session through your proxy and drive it from the dashboard. Its cookies and storage are saved when you end the session and restored the next time, so it stays signed in. Store the logins it creates in its vault, or hand a set of personas to a scheduled automation and let it run without you.

• Cookies and storage saved on release, restored on launch
• Per-persona credential vault with live TOTP codes
• Cron-scheduled automations across a set of personas
• Activity feed covering both what you did and what it did
