About Downloading Attachments for Secure Notes

Like all stored data, Secure Note attachments are locally encrypted and decrypted with a key that is never sent to LastPass, providing a secure storage option with the convenience of universal access. Adding attachments can be helpful in maintaining access to important documents in case they are misplaced or you lose access to a printed copy, such as a lost passport when traveling abroad.

Supported file types

LastPass users can add various file types as attachments to their Secure Notes that meet the following requirements:

  • Must be a supported file type: "csv", "doc", "docx", "odt", "ppt", "pptx", "txt", "xls", "xlsx", "pdf", "png", "gif", "jpg", "m4a", "mpg", "wav", "avi", "rtf", "html", "htm", "mov", "tiff", "tif", "jpeg", "wmv", "tsv", "zip", "rar", "log", "key"
  • Each attachment file can be up to 10 MB in size, and your total storage limits are dependent on your account type (i.e., Free users have up to 50 MB whereas Premium, Families, Teams, and LastPass Business accounts have up to 1 GB).

Compatibility for downloading attachments

  • Attachments are supported on all web browser add-ons and platforms, including the Premium user iOS and Android mobile apps. However, attachments cannot be opened from the Online Vault in a web browser (i.e., logging in to
    Note:   While the LastPass mobile apps are free, a Premium user account requires a paid subscription. Learn more.
  • For attachments in Chrome, Safari, and Opera, you must install the binary component via the LastPass Universal Installer.
  • Attachments are downloaded on demand so it takes some time to download from the LastPass servers. If you encounter an error opening an attachment when trying to open it the first time, close the error message pop-up and leave the Edit window open for a few minutes and then retry. The max waiting time is 5 minutes, but it should be less than 1 minute if your internet connection is strong and stable.
    Note: You cannot save an attachment to your machine/device unless you can open it first.
