[matt-livefront]

🎟️ Tracking

PM-27074

📔 Objective

The SDK added InitUserCryptoMethod.masterPasswordUnlock for unlocking the vault with master password unlock data, which was introduced in #1978. This uses that method for vault unlocking if the user has master password unlock data.

This replaces the approach used in #2027.
