The recipient won\u2019t need to do anything to decrypt the message and can simply click or tap on the email to read it.<\/p>\n<p>Every part of the process undergoes some sort of encryption. The connection between your computer and the server is encrypted, the contents of the email on the server are encrypted, and only the recipient has the correct key to be able to decrypt the message on the other end. Attachments are also secured.<\/p>\n<p>Domains that use @protonmail.com, @protonmail.ch, and @pm.me will use this high-level encryption. ProtonMail also allows you to use a private domain name with the service, so it\u2019s possible to use internal encryption on non-ProtonMail domains, too.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717702\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/purple_padlock.png\" alt=\"Email Encrypted Internally by ProtonMail \" width=\"650\" height=\"327\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>You\u2019ll know that an email has come from a ProtonMail account (and thus, that it\u2019s been encrypted internally) when you see a purple padlock in the \u201cFrom\u201d field next to your contact\u2019s email address.<\/p>\n<p>In order to communicate with someone securely, you might want to ask them to set up a ProtonMail account just for that purpose. They can even configure ProtonMail to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/protonmail.com\/support\/knowledge-base\/notification-email\/\">send them a notification email<\/a> whenever they receive a new secure message in ProtonMail.

PGP lets you send encrypted emails to people who aren\u2019t using ProtonMail\u2014as long as they have PGP set up.<\/p>\n<p>To send an email to a recipient using PGP, you\u2019ll need to know their public key (and to receive an email encrypted with PGP, the recipient must know your public key).<\/p>\n<p>Exchanging keys is an important part of this process. You can attach your public key to any outgoing email by clicking the \u201cMore\u201d drop-down button in the compose email interface and checking \u201cAttach Public Key.\u201d<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717703\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/attach_public_key.png\" alt=\"Attach Your PGP Public Key in ProtonMail\" width=\"650\" height=\"458\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>You can set this behavior as a default under Settings &gt; Security by enabling \u201cAutomatically attach public key\u201d in ProtonMail\u2019s preferences.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717704\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/automatically_attach.png\" alt=\"Automatically Attach Public Key to Outgoing ProtonMail Messages\" width=\"650\" height=\"342\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>The recipient will need to send their public key in order to receive your encrypted mail, so you\u2019ll have to communicate this to them.

It\u2019s certainly not for everyone, and signing up for a free ProtonMail account (which takes care of the key exchange for you, invisibly) might be an easier option. Or, rather than using PGP\u2014which can be complicated\u2014you can try the next method.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Option_3_Send_Password-Protected_Self-Destructing_Emails_to_Anyone\"><\/span>Option 3: Send Password-Protected Self-Destructing Emails to Anyone<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In addition to offering internally encrypted mail and great support for PGP, ProtonMail has one more failsafe for sending secure mail. It\u2019s a bit of a hack, but it works fine for your friends who insist on sticking to Gmail, Outlook.com, or any other email service provider.<\/p>\n<p>Here\u2019s how it works:<\/p>\n<ol>\n<li>You compose an email message like normal.<\/li>\n<li>The message is encrypted and locked behind a password of your choosing, and you hit Send.<\/li>\n<li>The recipient receives a message telling them that there is an encrypted email waiting for them, along with a link.<\/li>\n<li>The recipient clicks on the link, which points to a ProtonMail webpage with a password field.<\/li>\n<li>The recipient decrypts the message and is able to read it in their web browser.<\/li>\n<li>The message expires 28 days later (or sooner) without the contents ever being disclosed to any non-ProtonMail servers.<\/li>\n<\/ol>\n<p>This method is much simpler than setting up PGP or convincing your friends to switch email providers, but it\u2019s probably not practical for frequent communication.<\/p>\n<p>It\u2019s also worth noting that the recipient could pass the link on to anyone else (along with the password), which would compromise confidentiality. Never assume that a message is going to stay private just because you\u2019ve used a service like ProtonMail. You\u2019re also trusting the person you\u2019re emailing to keep your communications private.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717706\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/encryption_button.png\" alt=\"Encrypt for non-ProtonMail Users\" width=\"650\" height=\"124\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>To use the feature, compose an email in ProtonMail, then click on the \u201cEncryption\u201d padlock\u00a0icon in the bottom-left corner of the window. Enter and confirm your password before adding a password hint\u2014if you like. The hint is optional.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717707\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/non_protonmail_password.png\" alt=\"Secure Email with a Password\" width=\"650\" height=\"551\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>Click \u201cSet\u201d to encrypt the message, then click the \u201cExpiration Time\u201d hourglass icon if you want the message to expire sooner than in 28 days.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-717708\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/email_expiry.png\" alt=\"Set Email Expiry Date\" width=\"650\" height=\"554\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>You can then hit Send to send your email like normal.
