# Profile & settings

Manage your profile, language, login providers, and API keys.

Your profile and settings are reachable at any time, even without an active subscription. From here you manage your personal information, interface language, connected login providers, and API keys.

## Profile information

Update your account details from your profile. Your profile is one of the few areas available before you start a trial or subscribe.

## Language

Keryo is available in **English** and **French**. Switch the interface language from your settings.

{% hint style="info" %}
Keryo's free public tools and this documentation are available in both English and French.
{% endhint %}

## Login providers

You sign in with a **passwordless magic link** (enter your email, receive a link, and you're logged in). **GitHub** login is also available. You can review your connected login providers from your settings.

## API keys

For programmatic access, you can create and manage **API keys** in the web app. Keys are **scoped** and the secret is shown **once** on creation — copy it then, because only a masked preview is available afterward.

{% hint style="warning" %}
Managing API keys is web-app only (a logged-in session). A key cannot create or revoke other keys.
{% endhint %}

For full details on API keys, scopes, and authentication, see [Developers → Authentication](/keryo-docs/developers/authentication.md).
