What

Amazon Bedrock is Amazon's cloud service for running Claude models. When Claude Code sets up its connection to Bedrock, it now takes the API key from a different value, leaves it empty when there is none, and explicitly sets no separate auth token.

Why

This may change how Claude Code signs in to Bedrock when you use a bearer token, a key sent with each request.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtIt is not clear which setting the API key now comes from, or whether sign-in with `AWS_BEARER_TOKEN_BEDROCK` behaves differently.
