We have also added two additional login methods.

Since many users were concerned about access token regeneration every 24 hours, the third login method (PIN + TOTP-based login) eliminates this requirement. In this method, users do not need to pass an access token daily. They only need to provide their Dhan PIN and generate a TOTP key from the Dhan terminal, which does not require frequent changes.
