Authress introduces Vanishing Keys. Vanishing Keys is an open source one time secret store to enable ease of secret transfer.
In most cases, secrets should be generated and stored by the creator of the secret. And where possible secrets should only be generated at runtime. For this solutions such as a Key Management Service exists.
However, this is not always possible, and we need to transfer ownership of a secret from one person to another.
More details about how the Vanishing Keys service works is available in the documentation, but the important part of this new Authress service is that it provides 100% client side encryption. The secret and secret passphrase never leave your browser unencrypted.
