Where to find the mail password setting on your iPhone
Your iPhone stores passwords for email accounts in the Settings app, not in the Mail app itself. Open Settings, scroll down and tap Mail, then tap Accounts. You will see a list of every email account connected to your phone. Tap the account whose password you want to change.
Once you are in that account's settings, tap Account at the top of the screen. This opens a page showing your email address, incoming mail server details, and outgoing mail server details. The password field appears under both the incoming and outgoing sections — you may need to scroll to see it.
Key Takeaways
- Mail passwords on iPhone are stored in Settings > Mail > Accounts, not in the Mail app itself.
- You must enter the new password in both the incoming mail server section and the outgoing mail server section for the account to work.
- If you changed your email password at your provider's website (Gmail, Outlook, Yahoo, etc.), you must update it on your iPhone within a few days or mail will stop syncing.
- If Mail shows a password error after you update it, try signing out of the account completely and signing back in with the new password.
Updating the incoming mail server password
Under the Incoming Mail Server section, you will see a field labeled Password. Tap that field and delete the old password. Type your new password exactly as your email provider gave it to you — passwords are case-sensitive, so uppercase and lowercase letters matter.
If you recently changed your password at your email provider's website (such as Gmail, Outlook, or Yahoo), use that new password here. Do not create a different password just for your iPhone. After you enter the new password, tap the back arrow or swipe back to return to the previous screen.
Updating the outgoing mail server password
Scroll down to the Outgoing Mail Server section. You will see another Password field. Tap it and replace the old password with the same new password you just entered in the incoming section. The outgoing server almost always uses the same password as the incoming server.
After you update both passwords, tap the back arrow to save your changes. Your iPhone will test the connection to both servers. If the passwords are correct, Mail will resume syncing normally within a few seconds.
What to do if Mail shows a password error after updating
Sometimes Mail displays an error message even after you have entered the correct new password. The fastest fix is to remove the account from your iPhone and add it back. Go to Settings > Mail > Accounts, tap the account name, scroll to the bottom, and tap Delete Account. Choose Delete from My iPhone (not Delete from Mail Server).
Then tap Add Account at the top of the Accounts screen. Select your email provider (Gmail, Outlook, Yahoo, etc.) or choose Other if your provider is not listed. Enter your full email address and the new password. Your iPhone will verify the account and set up the connection fresh. This usually resolves password errors that linger after an update.
Differences between changing your password at your provider versus on your iPhone
When you change your email password on your provider's website — such as in Gmail's account settings or Outlook's security page — that change takes effect when ready on their servers. Your iPhone does not automatically know about it. You have a window of time (usually a few days) to update the password on your phone before the old password stops working and Mail cannot sync.
If you change the password directly in iPhone Settings, you are only updating what your phone knows. The provider's servers still have the old password on file. For this reason, most people change their password at the provider's website first, then update it on all their devices afterward. This keeps everything in sync.
Why your email provider might require a new password
Email providers ask you to change your password for security reasons — usually after a breach, if you have not changed it in a long time, or if you suspect someone else has accessed your account. Some providers also require a new password if you enable two-factor authentication or change your account recovery options.
When you change your password, the old password stops working everywhere — on your iPhone, your computer, your tablet, and any other device. This is intentional. It locks out anyone who might have the old password. You will need to update the password on each device you use to check email.
Frequently Asked Questions
Can I use the same password for multiple email accounts on my iPhone?
Technically yes, but it is not recommended. If someone learns that password, they can access all your email accounts at once. Most security experts suggest using a different password for each email account, and using a password manager to keep track of them.
What if I forgot my email password and cannot update it on my iPhone?
You will need to reset your password through your email provider's website first. Go to their login page, click "Forgot password" or "Can't sign in", and follow their recovery process. Once you have set a new password, come back to your iPhone and update it in Settings > Mail > Accounts.
Does changing my mail password on iPhone affect my password on other devices?
No. Changing the password in iPhone Settings only affects that iPhone. Your computer, tablet, or other phone will still have the old password stored and will need to be updated separately. The only way to change your password everywhere at once is to change it at your email provider's website.
Why does Mail keep asking for my password even after I updated it?
This usually means the password you entered does not match what the server has on file. Double-check that you typed it correctly — passwords are case-sensitive. If you are certain it is correct, try removing and re-adding the account as described above. If the problem persists, contact your email provider's support team.
