  • HTTPS: //onetimesecret.com not working from Turkey (curious)
    I am unable to reach https://onetimesecret.com from Turkey, I have to enable a VPN that takes me out of the country. I'm just curious: is it censorship? really? Any idea on how to know the reason? (DNS is the same, while traceroute clearly see tcp is droppet at 81.212.73.69.static.turktelekom.com.tr). - Source: Hacker News / 9 days ago
  • Our customer's IT guy sent us a password via email
    Https://onetimesecret.com for people that you don’t generally talk/work with. We use lastpass for internal stuff. Source: 11 months ago
  • Sending passwords securely
    My vote for onetimesecret.com we use a self hosted instance, allows for a single view before burning. Source: 11 months ago
  • Do you guys know 'Nodky' or even his YouTube [Need Info]
    They then take like 1 week to get to you and asks for your phone number to send the password, but they never send it to your phone number but instead sends you the link to your password (which was a https://onetimesecret.com/ link) and a .7z file with ur data. Source: 11 months ago

  • For the past 3 months in my spare time I was developing this list with Awesome Android Alternatives! Please check this out, you might find something useful, or maybe you can help me make it even better. Have an awesome day!
    Yes, of course you can. I am aware of this app but I have not yet fully tested it. I know about K-9 Mail too. Also not tested. Source: almost 2 years ago

    I agree because I need to test it. I am aware of K-9 Mail and FairMail though. Source: almost 2 years ago
  • Email send error javax.crypto.BadPaddingException: pad block corrupted
    I've rebooted quite a few times. Updated the app too. I don't use a VPN. I installed k9-mail to test and that works without problems. https://github.com/k9mail/k-9. Source: over 2 years ago
  • Gmail App Alternative focused on privacy?
    On Android the usual recommendations are FairEmail or K-9 Mail. Both are fully open source and privacy focused, it basically comes down to your personal preference. For them to work with your Google Account you will probably have to create an app password. Source: about 3 years ago
