# Sign up and log in

Nekodex uses your email & a passkey generated by your phone to create your on-chain wallet. Passkeys are secured by your device biometrics like FaceID or your fingerprint (if you only use a lockscreen PIN that is ok too).

## Device Requirements

* A mobile device supporting Passkey
* Recommended: iCloud Keychain or Google Password Manager to back-up Passkeys
* Mobile device lockscreen turned on using FaceID, fingerprint and/or PIN
* iOS 16+, Android 9+ 
* [More details here](https://passkeys.dev/device-support/#matrix)

## Sign Up

Nekodex only requires a valid email to create your account. Your phone will use your email to create a passkey, which is used to create and secure your account.

In the app, choose Sign Up and enter + verify your email address with an OTP code. When prompted, please choose to save your passkey in iCloud Keychain or Google Password Manager whenever possible. It should be the default option.

During signup, you will be required to confirm using your FaceID, fingerprint or PIN.

If you have trouble signing up, make sure your phone supports passkeys.

{% hint style="danger" %}
**Never delete your passkey**\
If you delete a passkey from your mobile device or iCloud/Google account, it may be lost forever. Your account will not be recoverable.\
\
**Use a reliable email address**\
If you lose access to your email, you will not be able to log into your Nekodex account.
{% endhint %}

## Login

1. Enter your account email and verify using the OTP code sent by Nekodex. You must be able to receive the OTP code to log in.
2. Complete login using the passkey for your Nekodex account. This passkey is created when you sign up and create the account. Passkeys are stored on your phone, and normally backed up automatically in your Google or iCloud account.
