Migrate Yahoo Mail to another email provider

1. 1

   Sign in to your Yahoo account

   Open your Yahoo account settings in a browser and go to the account security area. You will probably be asked to verify yourself with a code sent to your phone or recovery address.

2. 2

   Find the app password option

   In the security settings look for the section that lets you generate app passwords for other apps. Yahoo may ask you to turn on two-step verification first if your account does not have it.

3. 3

   Generate a new code

   Choose to create a new app password and name it something recognisable, such as "IMAP migration". Yahoo shows the code once, so copy it before closing the window.

4. 4

   Use it in the tool

   With Yahoo preselected as the source, enter your full address and paste the app password as the old password. Test the login; the tool counts your messages before moving anything.

5. 5

   Confirm the destination

   Pick the new provider, add the destination mailbox and open the confirmation message delivered to it. The copy runs from there, and you can follow its progress on the page.

The tool fills these in when you select Yahoo as the source. Addresses on other Yahoo domains, such as ymail.com or yahoo.es, normally use the same server, but check your account if the login fails.

Passwords are used once. They travel encrypted to an isolated job that copies the mail and is deleted afterwards. They are never stored, logged or sent back.

• "LOGIN failed" or "Authentication failed"

  This is the classic Yahoo answer when the normal password is used. Generate an app password and use that instead. Also check that the username is the complete address, with the domain, and that you did not paste a trailing space.

• The app password worked yesterday but not today

  App passwords stop working if you change your Yahoo password or revoke them. Generate a new one, replace it in the tool and retest. Old codes are not recovered.

• Yahoo asks for a verification code during the test

  A sign-in from a server you have never used can trigger an extra check on your account. Approve it from the Yahoo app or your recovery address, then try again within a few minutes.

• The connection times out or drops mid-copy

  Yahoo can slow down or cut long sessions. Run the copy again: it recognises what already arrived and carries on with the rest, so a restart costs nothing and creates no duplicates.

Yahoo folders such as Inbox, Sent, Draft, Bulk and Trash are copied like any others, and the tool matches them to the equivalent folders at the destination when it can. Messages you moved to the Yahoo archive keep their dates. Your contacts, calendar, notepad and Yahoo-specific filters live outside IMAP and are not copied. If you want them, export the contacts as a file from Yahoo and import it at the new provider before you close the old account.

• Free, no signup

  No account and no payment. It copies up to 10 mailboxes per batch.

• Passwords are used once

  They serve that copy and are never stored. Nothing is deleted from the source mailbox either.

• The destination must be yours

  We leave a confirmation message in the destination inbox. The copy starts only when you open it.

• IMAP migration tool

  Any source and destination, with every provider and the limits.

• iCloud Mail

  iCloud Mail with an app-specific password.

• Zoho Mail

  Zoho Mail and its regional servers.

• IONOS

  IONOS and the server for each country.

• Professional email at Hostbrid

  If Hostbrid is where the mail is going, see the email plans.
