VALID Passwords are often REJECTED on new Sign-In devices...
Yahoo, please let users KNOW, with a brief, automated email, as to why you are no longer accepting a user's perfectly valid Sign-In Password.
I hope Yahoo will simply send a brief email "PASSWORD REJECTED" and include a reasonable explanation. Devices I "secure" through other layers of protection still function normally. (Most of these other "secure" devices have been allowed to internally store that same, supposedly INVALID password and they ALL still automatially sign me in.)
I've had this happen numerous times when I've had to use a new device to access my mail via the yahoo.com/mail URL.
I appreciate the need for security, but this suggested Notification email would also allow ALL Yahoo fans and users to KNOW when ANY truly "invalid" password hackers are attempting to breech our personal accounts.
Thank you...! (And... a BLESSED and HAPPY NEW YEAR, to ALL of you...!)
