Hello There,
As we promised on TOTP implementation, here's the detailed doc on the TOTP Sandbox rollout - https://workdrive.fyers.in/writer/open/zq9bccec88bdfcc174af9a444cb5f769b01f3
Note: Once you enable TOTP from the beta link we provided in the doc, you can log in with TOTP on the web, mobile and the API sandbox env. Also, you disable TOTP from the same link.
