You can now import your accounts from K-9 Mail or Thunderbird for Android. Export your settings there to a .k9s file, then import it in Sterna when adding an account to bring over each account's servers, ports, security and identities at once, instead of typing them again.

Passwords are never in that export, so you sign in once per account after importing (with your password, or a Microsoft sign-in for Outlook). POP accounts are skipped, since Sterna is IMAP and JMAP only.
