A dangerous security risk, multiple login ID's
I have noticed that it's possible to login using alias ID's. That is a huge security risk.
I have also noticed that it's possible to login using the base ID of disposable email. That also is a huge security risk.
Anybody who steals your phone would hack in. Yahoo has to look into this security vulnerability very seriously.
An account having multiple Login ID's is a dangerous security risk.
The yahoo customer should be asked to choose one ID, either regular email ID, or alias ID as the login ID. That way, the account will be secure.
In fact, many banks follow this security measure. They ask the customer to create a nickname for the account and use that nickname to log in.
An account should have only one login ID. The rest of the alias ID's should be used only for email.
