The Keepser application has an autofill service for Android phones. This service allows the user to autofill the fields from the NFC device where the secrets are stored encrypted. Everything is done in a secure contactless way. Autofill works in principle with all applications used in your phone (like Facebook, Instagram, …) as well as web browsers.

To enable this feature, go to the application’s user settings and check the autofill box. A settings page should open with several choices, select the Keepser application. The application becomes your default autofill software.

With Xiaomi devices running MIUI 11 or more, specific steps are required to make autofill work.

• Go to your phone settings
• Find the app info (it is where you can manage the app for example force stop the app)
• Go to Other permissions (this option is located below Application authorization and may take a few seconds to show up)
• Enable “Display pop-up windows while running in the background”.

This feature allows user-entered fields to be autofilled into a phone from a Keepser NFC device. Keepser application supports many different types of input fields. Remember to update Keepser application with this feature to get the latest developments in autofill and autologin.

Now click on the field to be filled in, a “search” button should appear next to it. Click on “search”. Place your NFC device under the antenna of your NFC phone. Then select the password, ID or public key of a cryptocurrency address you wish to use to fill in the field(s). The fields will automatically fill in to authenticate you. Understood, that the secrets automatically entered in the fields are not saved in your phone. This is the ultimate protection. The secrets are stored only in your NFC device and used on demand by your phone without backup.

The Keepser NFC device authenticity check, developed by Freemindtronic, utilizes a unique digital signature:

1. Manufacturing Process: Each device is uniquely signed with a combination of physical and digital parameters during its production, making every device distinct.
2. Presentation to an NFC Terminal: When presented near an NFC terminal or phone, the system automatically triggers the authenticity verification.
3. Signature Verification: The detected signature is compared against a pre-validated database.
4. Result Notification:
   • A match confirms the device as authentic, allowing secure operations to proceed.
   • If there’s no match, a warning is displayed: “Wrong signature: Your device might be counterfeit,” preventing further use.

This Freemindtronic technology is crucial for:

• Preventing Counterfeiting: Ensures no counterfeit or unauthorized devices can access the system.
• Enhancing User Security: Guarantees that only verified Keepser devices can access and manage encrypted data.
• Building Trust: Users gain confidence knowing their devices are protected against tampering and forgery.

If your device displays a counterfeit warning:

1. Verify Purchase: Ensure the device was purchased from an authorized retailer.
2. Contact Support: If your device is suspected to be wrongly flagged, contact Keepser’s customer support immediately.
3. Cease Usage: Stop using the device until its authenticity is confirmed to protect your data.

• Secures against fraudulent device usage.
• Preserves the integrity of your encrypted data.
• Reinforces trust in the Keepser Cold Wallet system provided by Freemindtronic.
