CLAUDE_TRUSTED_DEVICE_TOKEN

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_TRUSTED_DEVICE_TOKEN is a Claude Code environment variable: Stores a token that marks the current device as trusted, likely enabling persistent authentication sessions without repeated re-authorization. Added in v2.1.86 and still present in v2.1.294. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_TRUSTED_DEVICE_TOKEN=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_TRUSTED_DEVICE_TOKEN": "<value>"
  }
}
