Claude Session Login

Manage multiple Claude sessionKeys and switch claude.ai logins in one click.

Claude Session Login is a lightweight multi-account session management tool for Claude. Paste or read your sessionKey, then save and switch accounts with one click—no need to repeatedly enter email verification codes to log in to claude.ai. Key Features: • Multi-account management — Set a name and avatar color for each sessionKey for a clear, organized list • One-click switching — Click “Switch” to write the cookie and automatically refresh any open claude.ai pages • Validity check — Batch-check all saved Keys with one click to see whether they are still valid, with expired ones clearly marked • Expiration reminders — Each Key displays the remaining days; accounts that are near expiration or expired are shown with a badge on the toolbar icon • Read local Key — Read the sessionKey of the currently logged-in account from the browser, display it fully in a popup, and copy it with one click • Open Claude.ai — Jump to Claude.ai with one click, or focus the existing tab if it is already open • Clear login — Requires two confirmations to prevent accidental clicks; saved accounts are not affected Security & Privacy: • The extension communicates only with claude.ai: it writes standard cookies and performs validity checks only when you actively initiate them • No analytics, no tracking, no data collection • Manifest V3 with minimal permission requests Security Notice: A sessionKey is equivalent to your account login credential. Please use only Keys that belong to you, and only on devices you trust.
