Where to change your password depends on which email service you use

You cannot change your email password inside the Mail app on your iPhone. Instead, you log into your email provider's website or app — Gmail, Outlook, Yahoo, or whoever hosts your account — and change it there. Once you change it, your iPhone will ask for the new password the next time Mail tries to check for messages, usually within a few minutes.

The steps differ slightly depending on whether you use Gmail, Outlook, Yahoo, or another provider. The common thread: you change the password at the source, not on your phone. Your phone then updates automatically.

If you have forgotten your current password, you will need to recover your account through your email provider before you can set a new one. That process is separate and covered in the FAQ section below.

Key Takeaways

  • You change your email password on your email provider's website or app, not inside the Mail app on your iPhone.
  • After you change your password, your iPhone will prompt you to enter the new one the next time Mail syncs, usually within minutes.
  • If you use Gmail, go to myaccount.google.com; for Outlook, go to account.microsoft.com; for Yahoo, go to account.yahoo.com.
  • Two-factor authentication adds a second security layer and is worth turning on if your email provider offers it.
  • If Mail stops syncing after you change your password, delete the email account from your iPhone and add it back with the new password.

How to change your Gmail password on iPhone

Open Safari or any web browser on your iPhone and go to myaccount.google.com. Tap Sign in and enter your Gmail address and current password. Once you are logged in, tap the menu icon (three horizontal lines) in the top left corner, then tap Security.

Scroll down until you see Password and tap it. Google will ask you to sign in again for security. Enter your current password, then tap Next. Type your new password twice — once in each field — and tap Change Password. You will see a confirmation message. Close the browser and open your Mail app; within a few minutes, Mail will ask you to enter your new password.

How to change your Outlook password on iPhone

Open Safari and go to account.microsoft.com. Tap Sign in and enter your Outlook email address and current password. Once logged in, look for Security in the left menu and tap it. Find Change your password and tap that option.

Microsoft will ask you to verify your identity — you may receive a code by text or email. Enter that code when prompted. Then type your current password once, followed by your new password twice. Tap Next and then Finish. Your Mail app will prompt you for the new password the next time it syncs.

How to change your Yahoo password on iPhone

Open Safari and go to account.yahoo.com. Tap Sign in and enter your Yahoo email address and current password. Once logged in, tap Account info at the top. Scroll down and tap Security, then find Change password.

Yahoo will ask you to confirm your identity using a code sent to your phone or recovery email. Enter that code. Then type your current password, followed by your new password twice. Tap Change password. Your Mail app will update within a few minutes and ask for the new password.

What to do if Mail stops syncing after you change your password

Sometimes Mail does not automatically recognize the new password. If you see an error message in Mail or if new messages stop arriving, you need to remove the email account from your iPhone and add it back. Go to Settings on your iPhone, tap Mail, then tap Accounts. Find the email account that is not working and tap it, then tap Delete Account. Confirm by tapping Delete from My iPhone.

Now tap Add Account at the bottom of the Accounts screen. Choose your email provider (Gmail, Outlook, Yahoo, or Other), enter your full email address, and when prompted, enter your new password. Tap Next and let your iPhone verify the account. Once verification is complete, Mail will sync normally and you will see all your messages again.

How to turn on two-factor authentication for extra security

Two-factor authentication means that even if someone learns your password, they cannot access your account without a second verification step — usually a code sent to your phone. This is one of the strongest protections you can add.

For Gmail: Go to myaccount.google.com, tap Security, scroll to How you sign in to Google, and tap 2-Step Verification. Follow the prompts to add your phone number. Google will send you a code by text or call each time you sign in from a new device.

For Outlook: Go to account.microsoft.com, tap Security, and look for Advanced security options. Tap Two-step verification and follow the steps to add your phone number or authenticator app.

For Yahoo: Go to account.yahoo.com, tap Security, and find Two-step verification. Choose whether to receive codes by text or through an authenticator app, then add your phone number or app.

Frequently Asked Questions

What if I have forgotten my current password?

You cannot change your password without knowing the current one. Instead, use your email provider's account recovery process. Go to your provider's sign-in page (myaccount.google.com, account.microsoft.com, or account.yahoo.com) and look for a link that says "Can't sign in?" or "Forgot password?" Follow the prompts to verify your identity using a recovery email or phone number, then set a new password.

Why does Mail keep asking for my password after I changed it?

Mail may not have received the update yet, or the account settings on your iPhone are incorrect. Wait five minutes and try opening Mail again. If the problem continues, remove the account from your iPhone (Settings > Mail > Accounts > select account > Delete Account) and add it back with your new password. This forces your iPhone to re-sync with your email provider's servers.

Can I change my email password on the Mail app itself?

No. The Mail app only stores your password and uses it to check for messages. To change the actual password, you must go to your email provider's website or app. Mail will then update automatically once you change it at the source.

Do I need to change my password on my computer too?

No. Once you change your password at your email provider's website, it takes effect everywhere — your iPhone, computer, tablet, and any other device. You only change it in one place: at your email provider.

What should my new password be?

Use at least 12 characters and mix uppercase letters, lowercase letters, numbers, and symbols (like ! or #). Avoid words from the dictionary or personal information like birthdays. A random combination is strongest — for example, "Kx9@mL2$vPq4" is much harder to guess than "Password123." Consider using a password manager to generate and store strong passwords.
