Sign in to Fernhill

Sample

This site: fernhill.example

Fernhill alex.morgan@example.com

01

Sign in from your browser

Connect the extension to your Sycryptic account with your master password or a passkey. Your vault stays end-to-end encrypted: it is unlocked inside the extension and its entries only travel as ciphertext over HTTPS. After it locks, a PIN you set opens it again.

02

Instant autofill on real sites

When you reach a login page, the extension surfaces matching vault entries. Pick one and fill username and password in seconds.

Use the Sycryptic icon in a field, then pick a login. Arrow keys, Enter and Escape work too

03

Your vault, one click away

Search passwords, notes and recovery codes from the extension popup, copy what you need, and add or edit a login without opening the website. Without a connection it opens an encrypted copy, read only.

Everything you need to stay productive and protected while you browse

The extension fills, saves and edits logins, and fills cards and identities into checkout and address forms. Notes and recovery codes open there to read, while attachments, sharing, emergency access and Secure Send are on the Sycryptic website.

  • Instant autofill

    Fill a login in one click on the site it belongs to, and cards and addresses into checkout forms. A login for another site is filled only after you confirm it.

  • Save as you sign in

    After you sign in on a site, the extension offers to save the login, or to update the one you have.

  • Password generation

    Create strong, unique passwords directly from your browser whenever you register for a new account.

  • Two-factor codes

    Code fields get the login's authenticator code, and the popup copies it in one click.

  • Locked when you leave

    The extension locks itself after a time you choose, and can clear copied passwords from the clipboard.

  • Shortcuts and right-click

    Alt+Shift+F fills the site's login and Alt+Shift+S opens Sycryptic. A right-click on a login field offers the same.
