OTPKEY Authenticator

OTPKEY Authenticator adds a multi-factor layer of security to your online accounts.

Many services and IT products support one-time passwords to protect your account. OTPKEY generates these codes on your PC, even when you are offline, and keeps them one click away in the Windows taskbar.

OTPKEY works with the online services you already use, including Google, Microsoft, Amazon, Facebook, GitHub, GitLab, Dropbox, Cloudflare, AWS and many more.
