Hi,
It is not like “giving away your passwords” because Zoho Vault ensures complete data privacy through the host-proof-hosting technology. Even people with the highest privileges in Zoho cannot access your passwords, because Zoho holds only the encrypted data. All encryption and decryption happen at the browser itself (at your end) and only encrypted data gets transmitted. Your passphrase is used as the encryption key and it NOT stored anywhere. You need to remember that and hence you alone can access your data. You may review the security aspects explained in our website: https://www.zoho.com/vault/application-security.html
And Zoho, as a company, has been in the market since 1996 and over 15 million users trust our products. Let me know, if you have more questions.
Thanks,
Bala
