Feature request: Multi-account support

[siraustin]

Use Case

Many Google Workspace users manage multiple accounts — personal, business, client domains, etc. Tools like gog support this with an --account flag that lets you switch between authenticated accounts seamlessly:

gog gmail search "newer_than:1d" --account siraustin@gmail.com
gog calendar list --account info@business.com

Current Behavior

gws stores a single set of encrypted credentials. Running gws auth login again overwrites the existing auth, making it impossible to work with multiple Google accounts without manual credential swapping.

Proposed Solution

Add multi-account support, e.g.:

# Auth multiple accounts
gws auth login                          # default account
gws auth login --account work@corp.com  # additional account

# Use specific account
gws gmail users messages list --account work@corp.com --params '{"userId": "me"}'

# List authenticated accounts
gws auth list

# Set default
gws auth default work@corp.com

Each account's credentials would be stored separately (encrypted), with one designated as the default.

Why This Matters

• Freelancers/consultants managing client Workspace accounts
• Users with personal + work Google accounts
• AI agents that need to operate across multiple accounts (e.g., OpenClaw bots managing email for different users)
• Anyone migrating from multi-account tools like gog

Love the project — the dynamic Discovery Service approach is brilliant. Multi-account would make it a complete gog replacement. 🚀

Great idea, shouldn't be too difficult.

In progress.

Can you take a look at #85?

+1 on this. My specific use case: I have both a corporate Google Workspace account and a personal Gmail account authenticated via gcloud. When running gws auth setup, both accounts appear in the account selector, which sets the expectation that switching between them should be straightforward. However, completing setup for a second account overwrites the first account's credentials.

The proposed --account flag approach would be ideal. Even a simpler gws auth switch command that re-uses already-authenticated gcloud accounts without requiring full re-setup would be a meaningful improvement.

For anyone following this: PR #85 implements multi-account support and is in review. I've also submitted #117 with a small fix for token cache cleanup during logout. Looking forward to this landing.

Looks like this got reverted, should this be re-opened?
