Selley Authenticator

Connect your resale marketplace seller accounts to Selley by capturing your login session. Passwords are never collected.

Selley Authenticator is the companion browser extension for Selley.ai. It lets you connect your own resale-marketplace seller or buyer accounts to your Selley workspace, so Selley can list items, sync inventory, and track orders on your behalf. This extension requires a Selley.ai account. It does nothing on its own. HOW IT WORKS 1. In Selley.ai, open a sales or sourcing channel and click "Connect with Selley Authenticator". 2. The extension opens that marketplace's official login page in a new tab. A banner shows which account you're connecting, along with a Cancel button. 3. You log in directly on the marketplace's own page, exactly as you normally would. 4. Once you're signed in, the extension passes the resulting session to Selley and closes the tab. Supported marketplaces include Poshmark, Fashionphile, Rebag and Brandear, among others. The full list appears inside Selley when you add a channel. YOUR PASSWORD IS NEVER COLLECTED You type your marketplace password into the marketplace's own login form. The extension explicitly excludes password fields — it never reads, stores, or transmits them. It reads the username or email you enter only to confirm you signed into the account you meant to connect, and cancels the connection if they don't match. SCOPED BY DESIGN Nothing is captured until you click Connect for a specific channel, and capture is limited to that one marketplace's domain. The extension does not monitor your browsing or read data from any other site you visit.
