How to update email password on iPhone, and the other one

You changed the password on your provider’s website, and now the phone asks for it every twenty minutes. How to update email password on iphone is a short answer with one field in it — and two things around it that decide whether the afternoon goes well.

Settings › Apps › Mail › Mail Accounts › the account › Account › Password

That is the field. Before you use it, the warning Apple puts at the top of both of its pages on this, because the shortcut people are usually pointed at is to delete the account and add it back.

“When you make an iOS or iPadOS backup in iCloud or iTunes, it backs up your mail settings, but not your email. If you delete or change your email account settings, previously downloaded emails might be removed from your device.”

Apple says this twice, at the top of two separate pages, and it is the reason to change the password rather than take the usual advice and delete the account. A backup will not bring the messages back, because a backup never had them. For an account left on the server that is a nuisance; for an account whose only copy of ten years of mail is on the phone, it is the whole story.

So: change the password in place. Deleting and re-adding is the heavier instrument, and Apple’s own wording covers both — changed account settings, not only deleted ones, can take downloaded mail with them.

Then the part that turns a two-minute job into an evening. The password you just set may not be the password the Mail app is asking for.

The password you just changedWhat you think Mail wants

The one you type into your provider’s website. Apple’s check is exactly that: “To check your email address and password, sign in to your email provider’s website.”

Which is a better instruction than it looks. It settles what the password actually is somewhere that will accept it, before you start typing it into a field on a phone.

A special passwordWhat Mail may actually want

Apple: ask your provider “if you turned on any security features or restrictions, like two-step verification, for your email account. You might need a special password or might need to request authorization from your email provider.”

So the right password can fail, and the fix is not on the phone at all. Apple sends you to the provider, twice, and names them as the ones who authorise the device.

That second card is the one that turns a wrong assumption into a lost afternoon. If your provider has two-step verification switched on, the account is arranged so that a password alone is not enough. Apple’s answer is not a trick on the phone: it is that you “might need a special password” — one the provider issues for this purpose — and it points you at them, because that password is theirs to give rather than yours to choose.

It is worth knowing this exists before you spend an hour convinced you are mistyping. A correct password can be refused for a reason that has nothing to do with what you typed. Apple’s phrasing is careful and worth taking literally: you “might need a special password or might need to request authorization from your email provider to send and receive email on your device.” Two different arrangements, both of which live on the provider’s site rather than on the phone.

Two free diagnostics before you change anything

The first of those three is the one that saves the most effort, because it decides which half of the problem you have. Mail that will not send and mail that will not arrive are separate faults with separate Apple pages behind them, and an Outbox that does not exist tells you the sending half is working before you touch a single setting.

And the setting that explains mail arriving in batches rather than when it is sent. Apple on Fetch New Data: “With iOS 11 and later, and iPadOS, Automatically is set by default. Your device will fetch new data in the background only when your device is charging and connected to Wi-Fi.”

Read that once and a familiar pattern stops being mysterious: nothing all afternoon, then eleven messages the moment the phone goes on charge in the evening. That is not a broken account. It is the default doing precisely what Apple documents, and the fix is a schedule rather than a password.

One last thing about where the account came from, because it changes what is at stake. Apple’s warning about downloaded mail matters most on accounts that keep their only copy on the device. If the account leaves everything on the server, removing it and adding it back costs you a download. If it pulled the mail down and stopped keeping a copy on the server, the messages on that phone are the archive. Knowing which you have is worth the two minutes it takes to look, and it is the difference between an inconvenience and a loss.

The floors below take it four ways: the field itself, the password that is not your password, the checks that cost nothing, and the mail that arrives late rather than not at all.

Where to start

Four ways in.

“Just tell me where the field is.”
Start at the field
“The right password is being refused.”
Go to the other password
“I do not know what is actually broken.”
That is the free checks
“It arrives, but hours late.”
That is late rather than never

The field

Four taps, and one decision before them: change the password in place, or remove the account and start again. Apple is unusually direct about what the second one costs.

The other password

The reason a correct password is refused. Two-step verification changes what the Mail app is allowed to do with a password, and the answer is issued by the provider.

The free checks

Three things to look at before changing any setting. Each one costs nothing and each one rules out half of the possible problem.

What this tower will not do

It will not tell you to delete the account and add it back as the first move. Apple warns twice that changed or deleted account settings can take downloaded mail with them, and a backup will not have it.

It will not pretend a refused password means you typed it wrong. Two-step verification makes a correct password insufficient by design, and the fix is issued by the provider.

And it will not send you to a mail app to solve a password problem. The account is the same account whichever program reads it, and a new app inherits the same refusal. What holds instead is simple: the warning about downloaded mail, the two-step verification note, the Outbox and Undo Send diagnostics and the Fetch New Data conditions are quoted from Apple’s own documentation, listed below.
