1. Sign in to webmail and open Preferences → App Passwords. In the Classic web client, open the Security tab.
2. Under Name this client, type a name you'll recognise later, for example iPhone 16 or Outlook on the office PC.
3. Under Allowed protocols, tick what the app uses:

   If you set the app up as…	Tick
   IMAP or POP (most mail programs, and iPhone "Other" accounts)	IMAP (or POP3) and SMTP submission
   An Exchange account on an iPhone, iPad or Android phone	ActiveSync
   Outlook for Windows	MAPI over HTTP
   An Exchange account in Apple Mail or Outlook for Mac	Exchange Web Services
   Calendars and contacts (CalDAV / CardDAV)	CalDAV / CardDAV

   Not sure? Tick everything the device might use. You can remove the password and make a new one at any time.

4. Click Create Password.
5. Copy the password straight into your mail app's password field. It's shown only once. The spaces are only there to make it easier to read, so you can type it with or without them.

Your email address, server (mail.redmail.com) and port settings stay exactly as they are. Only the password changes.

You can have up to 20 app passwords at a time.
