OTP login is the right default
The GST portal's OTP flow verifies possession of the registered mobile number or email. Any automation you adopt should respect that model — not bypass it with stored passwords on shared machines.
Security principles for firms
Treat OTP as a credential with a short lifetime. Staff should trigger login only when needed, complete filing in a focused session, and avoid sharing OTPs over unsecured channels.
- Never store OTPs in plain-text notes or group chats.
- Use dedicated filing accounts per team member where the portal allows.
- Audit who logged in, when, and which GSTIN was accessed.
- Prefer platforms that encrypt session tokens and expire them automatically.
Automating without cutting corners
GST Bharo's portal login flow prompts for OTP at the moment of authentication, uses encrypted storage for session handling, and logs each access attempt — so you gain speed without hiding who did what.
When to re-authenticate
Re-run OTP login after long idle periods, credential changes, or when switching between high-sensitivity clients. A few extra seconds of verification beats a compliance incident.
