All of it happens in Account Settings, in the account menu at the top of the sidebar.
Changing your email
Update the email field in Account Settings and save. This is the address you log in with and where Pincone reaches you, so keep it somewhere you actually check.
Changing your password
Same page — enter a new password and save. If you're changing it because you suspect it leaked somewhere, also consider regenerating your MCP token if you've connected an assistant: it's a second key to your library.
Forgot your password?
The login page has an I forgot my password link. Enter your email, and a reset link arrives shortly. If it doesn't show up, check spam, and make sure you're using the address your account was created with — the one your Pincone emails arrive at.
Signing in with Google
You can also log in with Continue with Google — no password involved. If you signed up that way and later want a password (say, for logging in where Google isn't handy), the password-reset flow above works: request a reset for your Google email address, set a password, and both doors are open from then on.
Locked out entirely?
Changed email providers, lost the old address, reset link going nowhere — email us from whatever address you do have, tell us what happened, and we'll figure out how to verify it's you.
