What is an app-specific password, and how do I make one?
Apple lets apps that are not made by Apple sign in to iCloud Mail only with an app-specific password. It is a password Apple creates for one app, so Mail~ never asks for your Apple Account password. It needs two-factor authentication on your Apple Account.
- Go to account.apple.com and sign in.
- In Sign-In and Security, choose App-Specific Passwords.
- Generate one named “Mail~”, copy it, and paste it into Mail~.
You can have up to 25 active app-specific passwords and revoke them one by one. When you change or reset your Apple Account password, Apple revokes them all, so make a new one and Mail~ asks for it. Apple explains it in Sign in to apps with your Apple Account using app-specific passwords.
Does Mail~ work with Hide My Email?
Mail sent to your Hide My Email addresses reaches Mail~ when iCloud forwards it to your iCloud Mail address. If you forward it to another provider, it never reaches iCloud Mail, so Mail~ does not see it either.
Apple documents replying from a Hide My Email address only in its own Mail app. Until that is proven to work from other apps, Mail~ does not reply from one: it tells you, and nothing is sent until you choose, so your real address is never revealed silently. Forwarding such a message goes out from your own address, after you confirm. More in Apple’s guide to Hide My Email.
Can I use Mail~ on several devices?
Yes. Buy once, use it on your Mac, iPhone, iPad and Apple Vision Pro. Mail~ keeps your app-specific password in the keychain, and if you use iCloud Keychain, Apple syncs it to your other devices. Open Mail~ on another device and it says “Using your sign-in from iCloud Keychain” and connects. Without iCloud Keychain, enter the app-specific password on each device.
Your labels follow you through your own iCloud, encrypted. Mail~ on Apple Watch shows the Inbox your iPhone sends it; it never receives your password.
How do I sign out?
In Mail~, open Settings and choose Sign Out…, then one of:
- Sign Out on This Device: mail on this device is removed. Your other devices stay signed in, and nothing changes in your iCloud mailbox.
- Sign Out on All Devices: the app-specific password is removed from iCloud Keychain. Mail~ on your other devices will ask for it again.
To stop Mail~ from reaching your mail at all, revoke its app-specific password at account.apple.com.
What do I need to run Mail~?
- An iCloud Mail account (@icloud.com, @me.com, @mac.com) with two-factor authentication on your Apple Account.
- iPhone with iOS 26 or later, or iPad with iPadOS 26 or later.
- Mac with macOS 26 or later.
- Apple Vision Pro with visionOS 26 or later.
- Apple Watch with watchOS 26 or later, paired with an iPhone that runs Mail~.
Why do new-mail alerts sometimes arrive late?
On iPhone, iPad and Apple Vision Pro, Mail~ checks in the background when the system lets it; alerts can take minutes to hours, and the app says so. Mail~ has no server of its own to push mail to you.
