The basic problem is I am unable to reach 'Credential Manager' as an Administrator to change this password. By clicking the 'show password' button I learnt that it is only alphabet part of an incomplete sentence. I was tempted to change my Yahoo a/c Password by 'Copy & Pasting' the one incorporated in 'Mail' App. There is no 'Manage App Password' as mentioned in 'Yahoo User Forum'. However, it provides only a ON/OFF toggle for 'Allow apps that use less secure signature'. I do have two-step/two-factor authentication on my Yahoo a/c. Have you tried deleting the Yahoo email account?I am able to log in to my Yahoo a/c through a Browser(Edge/IE). Afaik the extra ** are just to disguise the length of the password & not reflective of the actual password.ĭo you have any two-step/two-factor authentication on your Yahoo account? If so then you may require an app specific password to enter instead of your usual Yahoo password.
