# I can't sign in

What to try when your password doesn't work, your invitation has expired or the site says you've tried too many times.

**Wrong password?** Select **Forgot password?** on the sign-in page and enter your email. The email is called "Reset your Sustainable ERP password" and the link works for 30 minutes. Not there? Check your junk folder.

**Can't find your invitation?** Look for an email from "your company name via Sustainable ERP", for example "Northbank Mechanical via Sustainable ERP".

**Invitation link expired?** Ask your administrator to open your user and choose **Resend invitation**.

**Too many attempts?** You'll be asked to wait a short time before trying again. This protects your account.

**Signed in, but sent to the wrong place?** Engineers use the app, not the website. If the website tells you to use the app, your account is set up as an engineer. Ask your administrator if that's wrong.

**A customer using the portal?** Customers sign in on the same page and go straight to the customer portal. If your invite has expired or never arrived, ask the company to resend it, or to send you the link themselves with **Copy invite link**. See [Give a customer portal access](/portal/give-portal-access/).

**Work for more than one company?** You'll be asked which one to use after you sign in.

Still stuck? Your administrator can check your account in **Settings → Users**.
