Aegix Link: logins from your phone to this PC

Keep this page open, then send a saved login from the Aegix password manager on your Android phone. It appears here so you can copy it into the site you are signing in to. Your phone encrypts it for this browser only — the server just relays data it cannot read, and deletes each message on delivery or after 3 minutes.

No phone paired yet.

    Incoming logins

    Nothing yet. On your phone, open a login in Aegix Passwords and tap “Send to PC”. It shows here for 60 seconds.

    What the server sees

    • This PC’s random ID, its public key and a name like “Chrome on Windows”; the phone’s random ID and model name.
    • Each login only as encrypted bytes. The key to open them is created in this browser and cannot be exported, so the server cannot decrypt them.
    • A message is deleted as soon as this page receives it, or after 3 minutes if it is never picked up.
    • On this PC, a shown login hides itself after 60 seconds, and anything you copy is overwritten on the clipboard after 30 seconds (while this page has focus).

    Makes a new key and unlinks every phone.

    Aegix Link — questions answered

    Can CryoSim read the passwords I send?
    No. Your phone encrypts each login with a key that only this browser holds (P-256 key agreement, then AES-256-GCM). The server stores and forwards ciphertext it has no key for, and deletes it as soon as this page picks it up, or after 3 minutes if it never does.
    How do I pair my phone?
    Click “Pair a phone” on this page. On the phone open Aegix → Passwords → ⋮ → Link a PC and type the 6-digit code. The phone then shows a 10-digit fingerprint: pair only if it matches the fingerprint on this page. The code works once and expires after 5 minutes.
    Where is this PC’s key kept?
    In this browser’s own storage (IndexedDB) for cryosim.com, created as a non-exportable key: page scripts can use it but cannot read it out. If you clear this site’s data or use another browser, a new key is made and you pair your phone again.
    Does this page need to stay open?
    Yes. Logins are only shown while this tab is open. A login sent while the page is closed is deleted by the server after 3 minutes, so just send it again once the page is open.
    Does Aegix Link cost anything?
    It is free during early access. You need the Aegix Android app with its password manager to send logins.
