Your Account

Everything about signing up, signing in, and managing your Nexus-Catalyst account.

Creating an account

Every plan starts with a 14-day trial.

Go to app.nexus-catalyst.com/signup
Sign up one of three ways:
- Email + password
- Continue with Google
- Continue with GitHub
If you signed up with email, check your inbox for a verification link and click it. You can request a new link from the sign-in screen if it expires.

OAuth sign-ups (Google/GitHub) are verified automatically.

Joining a team? If a teammate invited you, use the link in the invitation email instead — it creates your account, verifies it, and adds you to the team in one step.

Signing in

Sign in at app.nexus-catalyst.com/signin with the same method you signed up with. All three methods land on the same account if they share an email address.

Forgot your password?

Click Forgot password? on the sign-in page
Enter your account email — we’ll send a reset link
Follow the link to choose a new password

Password reset applies to email/password accounts; Google and GitHub sign-ins are managed by those providers.

The Account page

Everything account-related lives at Dashboard → Account (app.nexus-catalyst.com/dashboard/account), organized in tabs:

Tab	What’s there
Profile	Your name, email, and profile details
Security	Password management
API Keys	Plugin API keys for the Claude Code hook plugin
Billing	Current plan, upgrade/downgrade, payment details
Data Export	Download your memories and account data
Danger Zone	Account deletion

Plugin API keys

The hook plugins (like @nexus-catalyst/cc-plugin for Claude Code) authenticate with a Plugin API key:

Go to Account → API Keys
Click Generate and name the key
Copy it immediately — the full key is shown only once
Add it to your shell profile:
Terminal window
```
export NC_PLUGIN_API_KEY="your-plugin-key"
```

Lost a key? Generate a new one and revoke the old — keys can’t be re-displayed.

Note: MCP connections (Cursor, Claude Code MCP, Claude Desktop) don’t use API keys — they sign in with your account via OAuth. Plugin keys are only for the hook plugins.

Plans and billing

See what each plan includes on the pricing page
Upgrade, downgrade, or update payment details under Account → Billing
Plan changes take effect immediately; if the dashboard still shows your old plan, log out and back in

Exporting your data

Account → Data Export lets you download your stored memories and account data. Export before downgrading or deleting your account if you want to keep a copy of everything.

Deleting your account

Account → Danger Zone → Delete account. This permanently removes your account and stored memories — export your data first.

What’s Next?

Quick Start → — store and recall your first memory
Claude Code Setup → — automatic memory for coding sessions
