Infisical is deprecating its Service Token and API Key authentication methods in favor of identities, which offer more expansive security controls, including role-based permission systems, IP allowlist capabilities, and short-lived access token properties. The team has released the concept of identities since December 2023, and now plans to move all programmatic access use-cases to identities by July 30th, 2024. Existing tokens created prior to that date will remain usable until July 30th, 2025. Clients are advised to switch from Service Tokens and API Keys to using identities by the deprecation dates, with updated client documentation available for reference.
