No password. Enter the email your API key was issued to and we send a one-time sign-in link. In the account you see your plan, usage and invoices, rotate the key, restrict it to your IP addresses, set a daily ceiling and turn on two-factor sign-in.

The link works once, for 15 minutes, and only from the network it was requested from. How we protect accounts and keys: security.
