Signing in to Field on your phone

You sign in on your first day, again when you switch phones, and now and then when the app asks out of the blue. Signing out is the part to be careful with, because of the work sitting on the phone.

Before you start

The shop arranges installation with us, so if Field isn't on your phone yet, ask your manager rather than hunting for it in the app store. Your manager adds you in Office under Admin, in the Who can sign in list, using the Google email you'll sign in with. That gives you access right away and sends you an email from BoltWright with the address to use. There's no BoltWright password to set, because you sign in with that Google account.

The first sign-in

Open Field and tap Sign in (Sign in to BoltWright on iPhone). The app goes straight to Google's sign-in page in a browser window, Google asks which account to use, you pick the email your manager added, and then you land back in the app. The detour through the browser means Field never sees your Google password.

The email has to be the one your manager added. If you pick a personal account, or one left over from another shop, you land back in Field with "That Google account isn't on BoltWright. Sign in with the work account your company invited." Tap Sign in again and choose the right account, or add it in Google's account list. If the right account still doesn't get you in, ask your manager to check the email in Who can sign in. Older versions of the app say "Sign-in was not completed. Please try again." (on iPhone, "BoltWright couldn't complete sign-in. Please try again.") instead; it means the same thing.

Do the first sign-in somewhere with a decent connection. That's when the phone loads your company's customers, sites and equipment, so that it all works later without signal.

You stay signed in

Day to day you don't sign in again; you open the app and you're in. A sign-in lasts until you've gone 30 days without using the app, or 90 days in total, and then Field asks you to sign in once more with the same account. Your saved work is still on the phone when that happens, so it costs you a minute and nothing else.

When it lapses in a basement

If the connection drops while Field is renewing your sign-in, the app keeps your saved work and tries again when there's signal. You can keep taking notes, photos and readings while sending and Bolt wait for a connection.

If Field shows "Sign in again", your saved work is still on the phone, and your route stays open. You can keep running your clock, marking arrivals and taking notes, photos and voice notes; they send once you sign in. Adding equipment and finishing a visit wait for sign-in. Once you have signal, sign in with the same account so waiting work can send. The office can't see it until it arrives, so if your manager is waiting on a report, a phone call helps. The phone won't let a different person sign in while it's holding someone else's saved work. It asks you to sign in as that person first, or to remove their saved work, because each person's work stays their own.

Signing out

Signing out removes everything BoltWright keeps on the phone: the company's records, your notes, photos and voice notes, and anything the office hasn't received yet. Before it does, Field asks "Sign out and remove local work?" (on iPhone, "Sign out and clear this phone?") and lists what's still unsent. Cancel is the safe answer. Anything the office already has is safe in Office, and anything it doesn't have is gone.

So don't sign out to fix a sending problem. If work isn't moving, open the app on a good connection and give it a minute, or call the office and tell them what's on the phone.

When the office removes your access

If a manager removes you from Who can sign in, your phones are signed out the next time they connect. Field says "This phone was signed out by your office" and removes everything on the phone, unsent work included. If you're the manager, check that the person's work has reached the office before you remove them.

Ten phones, and the laptop

A person can be signed in on up to ten phones at once. When an eleventh signs in, the phone that signed in longest ago is signed out, and anything unsent on it stays there until that account signs in again. If you replace your phone, sign in on the new one and carry on, and only sign out on the old one once its work has gone up.

Field is phone-only. Managers and the office use Office in a browser with the same work Google account, and a manager who also carries the phone signs in to Field with that account too.
