Is proton mail pop3 or imap

ProtonMail, a popular secure email service, uses a custom protocol called ProtonMail Bridge to connect to their servers. This protocol is not IMAP or POP3, but rather a proprietary protocol designed to provide secure and encrypted access to your email account.

When you set up ProtonMail on your device or client, you'll typically use the ProtonMail Bridge protocol to connect to their servers. This protocol allows you to access your email account securely and encrypts your emails in transit.

Here are some key differences between ProtonMail Bridge and traditional IMAP/POP3:

  1. Encryption: ProtonMail Bridge encrypts your emails in transit, whereas IMAP/POP3 typically use SSL/TLS encryption, which is less secure.
  2. Authentication: ProtonMail Bridge uses a custom authentication mechanism, whereas IMAP/POP3 use standard username/password authentication.
  3. Data storage: ProtonMail Bridge stores your emails on their servers, whereas IMAP/POP3 typically store emails on your device or client.

If you're looking to access your ProtonMail account using a third-party email client, you can use the ProtonMail Bridge protocol. However, keep in mind that not all email clients support this protocol, so you may need to use a compatible client or use ProtonMail's web interface.

Here are some compatible email clients that support ProtonMail Bridge:

Keep in mind that ProtonMail's custom protocol may not be compatible with all email clients, so you may need to check with the client's documentation or support team to confirm compatibility.
