What cookies are
Cookies are small files your browser stores when you visit a website. OTPVN uses cookies and browser storage so you can sign in, to keep your account safe, for support chat and, with your consent, for visit statistics.
Necessary cookies (always on)
Without these cookies the site does not work: you could not sign in or top up. They are not used for advertising.
- __Host-otpvn
- Keeps you signed in.
- __cf_bm, cf_clearance
- Blocks automated traffic and checks that you are a person (Cloudflare Turnstile).
- otpvn.*
- Browser storage: your cookie choices and a few display settings, such as a USDT deposit in progress.
Support chat (always on)
The chat window is always on the page so you can reach our support team at any time. When you are signed in, the chat recognises your account so our support team can answer faster; the identity check code is made by the OTPVN server and never reveals your password or balance.
- cw_conversation, cw_user_*
- Keeps your conversation with our support team on this browser.
Statistics (with your consent)
Statistics tools only run when you allow them and OTPVN has them turned on. The figures help us improve the site and are never sold.
- _ga, _ga_*
- Counts visits and the most viewed pages, not tied to your account.

You can change your choices at any time with the button below. You can also delete cookies in your browser settings; the site will then ask again.
