Documented steps E2B disabled access-token authentication (the E2B_ACCESS_TOKEN env var) on Aug 1, 2026; API-key auth is now the only supported path. Get an API key from the E2B dashboard keys tab; the same key the SDKs use, scoped to a project. Wherever you run the E2B CLI (CI/CD, containers, servers, scripts), replace the E2B_ACCESS_TOKEN env var with E2B_API_KEY and delete the token line. Upgrade the CLI to v2.12.1 or later (latest recommended) so it authenticates with the API key alone. With E2B_API_KEY set, run CLI commands directly - you do not need to run 'e2b auth login'; the API key already targets the right project. If using the V1 template build system (which authenticated with the now-disabled access token), migrate to the V2 build system which uses E2B_API_KEY. Known gotchas Any request still authenticated with an access token now fails - there is no grace period after Aug 1, 2026. This silently breaks agents/CI that set E2B_ACCESS_TOKEN and never switched; the failure is an auth rejection at request time. SDK users are unaffected (SDKs always used API keys); the break is CLI + V1-build token auth. Interactive login commands 'e2b auth login' and 'e2b auth configure' are separate and unaffected - only token-based auth is gone. Official sources: E2B docs migration/access-token-deprecation page and the E2B changelog.
