  • Is it a good idea to use Bitwarden for OTP?
    2FAS is a very solid MFA; Bitwarden is designed to be a password manager, so I wouldn't suggest using it as a 2fa. Keep it separate imho. Source: 5 months ago
  • Ask HN: How to plan the big move from Android to iOS?
    > Is there anything as good as Firefox with UBO? The DuckDuckGo iOS app blocks ADs and trackers. Also ADGuard Pro can block stuff at the network level. It only costs $10.00 for a one time purchase. > My main concerns are will 2FA break? Make sure to export your QR code TOTP seed images into a new iOS app. Most TOTP apps allow you to do this. I like the app 2FAS[0]. > Can I keep using Google for photos and docs or... - Source: Hacker News / 5 months ago

  • [Data-Mining] Upcoming tunnels from the May 23 patch
    A quick google tells me that Duo is a 2FA service from Cisco. Maybe that's what Anet is using to manage the 2FA in the launcher behind the scenes? Source: 11 months ago
  • what do you use for ssh brute force protection: fail2ban or sshguard ? or something else ? for ubuntu and fedora
    I have Duo (https://duo.com) enabled on my internet facing SSH server. It sits behind sslh on port 443 and uses public key authentication only. Source: 12 months ago
  • Duo MFA with Serverless API Gateway for authentication
    Our organization uses Duo, which is an MFA tool that competes with Okta. I created a serverless application with API Gateway and Lambda that gives users access to Salesforce resources where they can directly update records. This was a workaround for getting around Salesforce community clouds expensive community licenses. Source: about 1 year ago
