If you decide not to upgrade some of your devices, those devices using NetSfere version 6.6 or older will not be able to decrypt the new conversations that use quantum-proof encryption. You will still have access to all your older conversations. NetSfere recommends that you update all your devices to version 6.7 or later.

NetSfere quantum-proof encryption requires version 6.7 or later. Previous NetSfere version 6.6 or older will not be able to decrypt the new conversations that use quantum-proof encryption. You will still have access to all your older conversations. NetSfere recommends that you update all your devices to version 6.7 or later.

The latest NetSfere apps can be found at https://netsfere.com/downloads.

Note: NetSfere version 6.7 will soon become the lowest supported app to facilitate the transition of all users to quantum-proof encryption.
NetSfere mobile, desktop, and web app version 6.7 with quantum-proof encryption will become available starting Mar 10, 2025.
If you are using more than one device with NetSfere, you must re-authenticate yourself on each device to facilitate the transition to quantum-proof encryption. Alternatively, you may logout and re-login on your other devices.
As a last resort, if you have forgotten your password, you can reset it. Please keep the following in mind when you are resetting your password.
  1. The password reset link is valid for 1 hour.
  2. Resetting your password regenerates your encryption keys. After reset, you may notice some conversations remain encrypted. These conversations will decrypt eventually once the NetSfere app synchronized your account. In some cases, you may have to wait for other conversation participants to access their app to help complete the synchronization process.
  3. If you have any self-conversations (conversations where you are the only participant), you must export that data prior to resetting your password or you may lose access to that conversation/chat.
You can reset your password here.
