100 credits a month, no credit card required. Failed builds and runs cost nothing.

## Connect a portal once, and every method and workflow can use it

### Connect an account where you build

Ask for a method on a portal that takes your login, and pick the account it should use on the same screen.

### Keep every login apart with a label

Regional, subsidiary or per-client logins on the same site each get their own label, and you choose the account on each run.

### Sign in once, two-step codes included

You sign in through the portal’s own flow, and Fous seals the login with AES-256. It is never returned by the API or written to logs.

### Your code holds a Fous key and nothing else

Name the connection in a run or set a default for the site. The session stays in Fous, and when it expires Fous signs back in so scheduled runs keep working.

## Frequently asked questions

### Where are our logins kept?

In Fous, sealed with AES-256, and never returned by the API or written to logs.

### Does two-step sign-in work?

Yes, emailed codes, sign-in links and phone approvals, in Studio or relayed from your code.

### What happens when a session expires?

Fous signs back in with the sealed login, so scheduled runs keep working.

### Can we connect several accounts on one site?

Yes, each with its own label, and you pick the account per run.

### What if a portal needs a person?

The connection shows it needs attention, and runs return a link to sign in again.
