The problem

Every day, we give away our identity just to participate online.

Access. Interaction. Personalization. The internet still asks for a name, email address, phone number, or shared login before it will recognize and serve us.

Think of making a house key

Every new key starts as a blank.

When you make a new house key, you start with a blank key. An image and a phrase become that blank mementom key.

Your key ring

To get started, add two keys to your key ring.

You only need a few keys to open a world of possibilities. You can easily add, remove or change keys at any time, without losing the value of what the keys do.

YOUR PRIVATE KEY RING Two keys to get started

How it works

A key on your key ring is blank until they encounter a lock on a partner site.

If you have rights to open that lock, one of your keys is temporarily "engraved" for that lock. Mementom asks for the key image by showing you the key phrase you created for it. While lock is unique, any key on your key ring is chosen at random to open it. That's simple and secure identity free access that you control.

A private key ring that stays yours.

  • Use one key ring across all sites and apps.Each site gets its own unrelated relationship. There is no cross-site tracking.
  • Keep identity out of the exchange.Receive access and personalization without providing an identifying address to mementom.
  • Replace a key whenever you want.Replace any one memkey without replacing your key ring.
  • Just provide the matching image.mementom provides the phrase, asks for the image that matches it, and keeps track of the key assignment for you.

How the privacy holds

Your picture stays with you. Your browser sends derived numeric evidence. It never sends the picture itself.

Your identity never enters. Mementom does not require a name, email address, phone number, or identity profile.

Companies remain separate. Each site or app receives only its own private relationship and the answer to its own request.

Add mementom to your site or app.

Private personalization for return visits. Fresh approval for exact actions.
