Authentication

PlainHub supports three authentication methods:

• gh CLI import (recommended): plainhub auth --from-gh
• Manual PAT: plainhub auth — opens GitHub token settings
• Web UI: Enter PAT directly in the browser

Tokens are saved to ~/.config/plainhub/token with 0600 permissions (owner-only read/write).

Security

• Tokens are stored locally with restrictive file permissions (0600)
• URL fragments (#token=...) are never sent to servers per HTTP spec
• Fragments are cleared from browser history immediately after use
• No intermediary servers — browser communicates directly with GitHub API
