Sign-in problems

How sign-in codes work, what to do if your code doesn't arrive or doesn't work, the No access page, and resetting a password.

Updated 11 October 2026

How sign-in works

Go to your company's address (e.g. yourcompany.engineeros.uk) or app.engineeros.uk, then either:

  • Sign in with a code (the default): enter your email, tap Email me a sign-in code, then type the 6-digit code from the email and tap Verify and sign in. No password needed.
  • Sign in with a password: tap Sign in with password instead.

You stay signed in for 90 days on that device. On a new phone or computer, just request a new code.

The code didn't arrive

  • Wait a minute, as it can take a little while. Then check your spam or junk folder. The email comes from noreply@engineeros.uk with the subject "Your Engineer OS sign-in code".
  • Check the email address you typed. For security, the screen always says it has sent a code, even if the email doesn't match an account. If you're not sure which address your company used, ask your admin.
  • Tap Send a new code. Wait at least a minute between requests: if you ask again too soon, no new email is sent. You can request up to four codes an hour.
  • On a work email, your company's mail filter may be holding the message. Ask IT to allow email from engineeros.uk.

"That code is incorrect or has expired"

Codes last one hour and work once. If you've requested more than one, use the code from the newest email. Otherwise tap Send a new code and try again.

"This link is no longer valid"

You'll see this if you followed an old link from an invite or password email. Links expire after an hour and work once. Request a sign-in code on the same screen instead.

"This account has been deactivated"

Your admin has switched off your account. Ask them to reactivate it.

"No access"

If you see No access ("You are signed in, but your account is not a member of an active organisation…") after signing in, it's usually one of these:

  • Wrong company address. You've signed in at another company's ….engineeros.uk address, perhaps from an old bookmark. Check the address bar and ask your admin for the right one.
  • You belong to more than one company. Sign in at the specific company's address rather than app.engineeros.uk.
  • Your access has been removed by your admin.

Tap Back to sign in to try again.

Forgotten your password

You don't need it: sign in with a code instead.

If you want to use a password and have forgotten it, ask your admin to reset it (see below). There's no "forgot password" link on the sign-in page.

For admins: resetting someone's password

  1. Go to Engineers, find the person, and click Reset Password.
  2. Engineer OS creates a temporary password and shows it once. No email is sent.
  3. Copy it (or use Copy email + password + login instructions) and send it to them by WhatsApp, text or in person.
  4. When they sign in with it, they're asked to choose their own password before they can do anything else.

People who haven't accepted their invite yet show Resend invite instead.
