Different machines

Recently I gave an access of my account to my friend to take trades on behalf of me. But now I changed password and pin. Will he be able to log in at his end with old password pin etc.

No he won’t be able to login with old credentials.

Hi @9550650715 Welcome to Dhan community.

It’s always recommended to not share your account password or PIN. As already mentioned by @t7support your friend won’t be able to login, that aside you can visit the Manage Sessions section of your app or web, and forcefully terminate all other sessions.

Also request you to change your mobile number as username, its a public forum and visible to all.
