The Polkadot Developer Signer is an account manager developed by Parity. In this article, you can learn where to download it for Chromium-based browsers (Chrome, Brave, Edge) and Firefox.

!!! warning "IMPORTANT"

    The Polkadot Developer Signer is an account manager **meant for power users and developers.** There are several user-friendly browser extensions that support a lot of features right from the extension. Discover them in [this article](where-to-store-dot.md).

**Adding your accounts in the browser extension is highly recommended, as it has many advantages:**

1. It provides better security than using the Web UI 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 Polkadot ecosystem

!!! danger "READ THIS FIRST!"

    There are from time to time phishing extensions in the web stores that pose as Polkadot wallets. Beware not to fall for these scams.
    Download the Polkadot Developer Signer **only** from the links below and **DO NOT** create accounts or enter your mnemonic phrase in any extension, site, or app that you don't trust explicitly.
