Login & Authentication

Fourplex is passwordless — no password needed. Enter the email already associated with your Fourplex account and choose Email me a code. We’ll email you a 6-digit code (it’s also in the email’s subject line, so you can often read it straight from your phone’s notification). Type it on the screen where you asked for it. The code expires after 1 hour. If you’re new to Fourplex, use the sign-up flow first to create your account.

On an iPhone, iPad, or Mac using Safari with Apple Mail, your device may offer to fill in the code for you as soon as the email arrives — just tap the suggestion above the keyboard or in the code box.

Choose Sign up on the login page and enter your email. We'll email you a 6-digit code; type it in, then fill in your HOA's details to start your 14-day free trial. You don't need an access code or invite. If the sign-up tab shows a request form instead, sign-ups are by request for a short time: fill it in and our team will be in touch soon to set up your trial.

I didn't receive my code. What should I do?

Check your spam or junk folder first. Sign-in emails can take up to 2 minutes to arrive. Make sure you’re using the email address associated with your Fourplex account. If you were invited to join an HOA, click the button in your invite email again (it works until the invite expires), or go to /login with the invited email; either way we’ll send you a fresh code back into onboarding.

Many work and school email systems (for example, a university .edu address) run a security scanner that automatically opens every link in incoming mail. A one-click sign-in button was used up by that scanner before you could click it, which made the code fail too. Sign-in emails now contain only the code, so scanners can’t use it up.

My code says it’s invalid or expired. What should I do?

Check that you typed the code from the newest email, on the same screen where you requested it, within an hour. Each code works once. Choose Request a new code to get a fresh one.

Is the 6-digit email code the same as two-factor authentication?

No. The 6-digit code in your sign-in or sign-up email is how you finish passwordless login on this device. An authenticator app code (Account → Security) is a separate second factor. After you sign in with the email code, Fourplex still asks for the authenticator code if you have 2FA enrolled. If your password manager (such as 1Password, Bitwarden, iCloud Passwords, or Google Password Manager) stores your Fourplex authenticator code, it can fill it in on that screen for you.

I entered the wrong code too many times. What now?

After five incorrect codes, that code stops working and the field is disabled. Fourplex does not send a replacement automatically. Choose Request a new code, complete verification if asked, and use the new email.

How do I sign out?

Visit /logout (or /api/auth/signout) in the same browser — that ends the session and returns you to the login page. Board members can also open the avatar menu in the top-right corner and choose Sign out. Residents can sign out from Profile in the member portal.

Can multiple people use the same email?

No — each email address is tied to one Fourplex account. If multiple people in your household need access, each person should use their own email address and be invited as a separate member.
