Aptos implements authentication for transactions using an access key without a password
The new authenticator repeats the ease of use of services such as Apple Pay or Google Pay
Aptos Labs has introduced a new way to sign transactions in its first-level blockchain network (L1) using an access key (Passkeys), which eliminates the need to set passwords, The Block reports. Avery Ching, co-founder and technical director of the platform, explained that the developers have made changes to the blockchain and created a new authenticator on Aptos, which will accept the transaction, the signature of the access key, the public key and confirm the operation using this information. This will allow the user to sign transactions with their own key, he added.
Currently, when users create an account in a crypto wallet, a long code or private key is generated. According to Ching, this key is usually encrypted with a password that is set by the user himself. If you forget this password, you may lose access to your wallet. At the same time, using a key, logging in becomes possible without a password, usually via Touch ID or Face ID.
According to Ching, access keys are more convenient to use and replicate the ease of use of services such as Apple Pay or Google Pay. So, users will be able to store the private key for the Passkeys account on their device and synchronize it with a backup provider (for example, iCloud or Google Password Manager). Then, when they want to sign the transaction, they can use the access key directly instead of sending a request to the service.
Other cryptocurrency projects, such as Dynamic Wallet and Turnkey, also provide key authentication. However, unlike Aptos, where users store a private key on their device, Dynamic Wallet and Turnkey store data in systems such as Amazon Web Services Nitro Enclave, Ching noted.
