In this article you will learn how to restore your Cere account in the Polkadot{.js} extension either with your account's 12-word mnemonic phrase or its JSON file and password.

We highly recommend that you add your accounts in the browser extension, as it has many advantages:

1. It provides better security than using the Cere Explorer directly

2. Your browser won't "forget" your accounts if its cookies are cleared

3. It allows you to interact with any Web 3.0 compatible site in the Cere and Substrate (Polkadot) ecosystem.

4. The extension recognizes all known Cere, Polkadot and other Substrate scams and alerts you when you try to visit a known scam site. This will help you protect yourself and your funds.
