You sign in on Fastmail’s own page, in the phone’s browser. The app never sees a password. That one sign-in is all the app needs.
- Tap Sign in with Fastmail. Fastmail’s sign-in page opens in your browser.
- Type your Fastmail address, your password and your two-factor code, exactly as on the web.
- Approve access for Opensolr Mail. You are back in the app and your inbox fills.
No IMAP or SMTP settings, and no app password. To add another account, open Settings → Mail Accounts → Add account and do the same with the other address. Each account can be signed in again or removed from the same place.
Every part of the app works without it: the inbox, sending, notifications, notes, calendars, search (Fastmail’s, chosen in Settings → Preferences → Search) and contacts. Skip this section if you only want a Fastmail client.
An Opensolr account adds search by meaning, AI answers, search inside attachments and pictures, everyone from your mail in Contacts, and new mail pushed at once instead of every 15 minutes. Connect one whenever you like: from the search screen, from Settings → Opensolr Account, or on the first screen of the app. With Fastmail search chosen and no Opensolr account, Settings does not show the Opensolr sections: connect from the search screen.
- Tap Connect an Opensolr account. The Opensolr login opens in your browser.
- Sign in, with two-factor authentication if you use it, and approve the app.
- The app creates your mail index and starts filling it in the background. See Your mail index.
No Opensolr account yet? Create one, free, no card. Signing out of Opensolr in Settings turns the Opensolr search off and leaves the rest of the app as it is; Fastmail search works without it. A lost phone can be signed out from opensolr.com: see Signing a phone out.
