# Introduction to Passkeys

{% hint style="warning" %}
Passkeys are required for trading on Defined. We highly recommend reading this document, in addition to ones specific to your preferred device, to better understand how they work before creating one and using our platform. &#x20;

\*NEW\* As of Aug 2025, we have updated our authentication methods through Turnkey which will limit the need for inputting your passkey. While passkeys are still used behind the scenes, fewer prompts mean a more seamless trading experience with fewer interruptions. If you need any assistance with your account, be sure to reach out to our team.

## What are Passkeys and how do they work?

Passkeys are a new kind of login credential that is growing in popularity across websites, apps, password managers, and operating systems due to their unmatched security and convenience.

Locally stored on a trusted device of your choosing, Passkeys provide a fast and secure method for accessing your accounts, with the added protection of biometrics or a PIN.

Passkeys work by sharing a public key with sites or apps you want to sign in to, and then validating your credentials against a private key that is stored locally on your device.

Your Passkey-protected accounts are highly resistant to phishing attacks as attackers would require access to your Passkeys and a way to authorize the device that stores them.

## Using your Passkey on Defined

Passkey authorizations are required for the following actions on Defined:

* Unlocking Trading Sessions (you may also choose the length of your session)
* Withdraw/Transfer funds
* Export/View private keys
* Creating/Importing new wallets

As you can see, Passkey authorizations are not required very often, allowing for an unobtrusive trading experience (unlike trading on a DEX such as Uniswap, which requires numerous wallet authorizations).&#x20;

{% hint style="warning" %}
Your Passkey and generated wallets are unique to the wallet/account connected to Defined. Connecting with a different wallet/account will require a new Passkey to access trading functions.

## Telegram Bot Considerations

Once you have [connected your account](https://docs.defined.fi/defined-docs/defined-classic/telegram-bot-guide) on [@defined\_bot](https://t.me/defined_bot), you will instantly be able to manage your trades wherever you use Telegram.&#x20;

Passkeys are not required while trading on Telegram, however, if your active trading session expires, you would need to unlock trading at [defined.fi](https://defined.fi) (or in App) with your Passkey device in order to continue trading.

Additionally, any functions that require a Passkey are not possible on Telegram. Our Telegram bot is designed to be a companion app and should be used in conjunction with our web platform to get the most out of your trading experience.&#x20;

Important! If you lose access to your Passkey/Passkey device and do not have a recovery email attached to your account, you will not be able to access funds in your Defined wallets and we will not be able to recover your funds for you. Users may at any time export their wallet's private keys (Passkey required) for recovery purposes, however, they must do so **at their own risk** as we cannot guarantee private key safety once exported.
