In this post, let us take a look at services that allow you to send sensitive information over email. One time passwords, address or any other information that can be read easily by others. If you want to share passwords via email, here are some examples of services can be useful. Note that this method is recommended for one itme use passwords only.

Background: Password via email

A few weeks ago, I signed up with a service provider. They sent me an automated email asking me to confirm my email account. Upon confirmation, they sent me account details. To my surprise, the password to my login was mentioned in plain text!

As we enter the third decade of the current millennium, this practice should be stopped immediately. But what if your provider does not want to upgrade systems? You can either bid them goodbye, or encourage them to use a service that sends one time passwords. Or a service where the information is encrypted before it is sent.

Sending other sensitive information via email

Let us say you want to communicate information across to a user, a friend, or a near and dear one. Would you do so in plain text? Your spouse’s birth date, etc. are some of the more innocuous examples. Others include medical records, or insurance details. You can let your imagination run wild on this one.

Would you send this information via email, or use a third party service? Most of you would prefer the latter!
I looked up some information on the latter, and came up with the below list.

Sending information via email: Third party services

Below is a list of services that are free to use. There are paid options also available. While I am not a big fan of *free* services, I thought that for everyday use, the below services were more than adequate.

Quickforget.com
This is a service form Automattic, the folks behind WordPress. Quickforget lets you store the information on their site temporarily. This could be a one time password, or information that can only be accessed by users who have the secret link.

Revealit.me (Service Discontinued)

Using revealit.me, you post your message, and a link is generated automatically. You can send the link to the recipient via email, or any other means. The recipient can read the message by clicking the link. The message is a one-time use, that is, if you share the link with multiple users, or refresh the page, the message gets deleted.

One Time Secret
You can create a link for a one time use using this service (as the name says!) You can create a random one time message, and send the link for that message to the recipient. They can reply to you in a similar fashion. You can also encrypt a short message and set a password. the reader will have to enter the password in order to read that message. That way, even if someone surreptitiously gets hold of the link, they will not be able to read the message. Other features includes setting a time limit for the message (for e.g. message will self expire after 7 days). Learn more about onetimesecret here.

Sites like alternativeto have a list of current and former services.

Safenote is an ad supported free service that allows you to send files and notes. A self destructing Private link is another option they offer.

temp.pm allows you to send AES-256 encrypted private messages. It is a free service but they welcome donations.

Yopass offers a self hosted option to the above services. You can also use their website. The messages can self destruct after one time read, or with a set time limit.

Nohistory.fyi was site that allowed you to send formatted email or messages, set passwords, one time read messages, or set a timeline before the message self destructs. The site mentions that the product is in early stages of development, the tech stack is based on AWS.

Typewriting.ink I saw this one on Betalist, and thought of adding it to this post. While not specifically designed for secure messaging, this site does offer that function.

Update: This site is no longer operational.

Noteworthy Mentions

You can use one time use email accounts to send the information, though the purpose of existence for such accounts may be different than the above services. Here are a couple that I have used often in the past. In a future post a more extensive coverage of such services is planned.

Temp Mail

Guerilla Mail

Summing it all up

One can think of many useful and innocuous ways of using the above (or similar) services. Some could be for fun. Others for financial information, medical records, account logins, etc. Of course there can be some nefarious ways, but let us focus on the legitimate ones, and appreciate that such services exist.
