Otpkey Authenticator adds a second layer of security to your online accounts. It generates one-time passwords (OTP) for two-factor authentication (2FA / MFA) right on your device, even when you are offline.

It works with the services you already use — Google, Microsoft, Amazon, AWS, GitHub, GitLab, Facebook, Instagram, Dropbox, Slack, PayPal, Cloudflare and many more — and with any service that supports the standard TOTP or HOTP protocols.
