check the following scenarios
if you are using an older pop or imap email application
if you are setting up your yahoo mail account in an older email application that uses imap or pop, you may see “server password changed” or “authentication failed ” error message. This error occurs because those email applications use an outdated security protocol to which yahoo has disabled access.
if you are using yahoo account key or two-step verification
If you have enabled account key or 2-step verification for your yahoo mail account, you will need to generate an app password to access your yahoo mail account in a third-party email client. to generate an app password, you will need to go to account info > account security > manage/generate app password.
if you have added an additional email address to your yahoo mail account
always make sure you have verified the additional email address you add to your yahoo mail account. having an unverified email address can lead to problems like a 553 error code when sending a message using a third party email application. you will need to follow the on-screen prompts in the email account where you received the verification message.
