# Zivver Chrome Extension for Gmail - User Manual

## Introduction

How to install and use the Zivver Chrome Extension for Gmail?

The Zivver extension enables you to securely send emails from Google Gmail in Chrome.

With Zivver, you can easily and securely share privacy-sensitive information with colleagues, customers, patients, and other recipients. If you send a message securely, only you and the recipient(s) can read the message.

### Reading guide

You can use this manual as a reference. You don’t need to read it from start to finish to email securely. Each chapter stands on its own. In each section, we provide steps to get started with the Zivver Chrome Extension for Gmail.

### Questions?

Contact the service desk of your organization.

## Install

To email securely from your Gmail account, you need the Zivver Chrome Extension for Gmail and a Zivver account.

Note

Your account must be part of a Google Workspace organization. The Zivver Chrome Extension does not work with a personal Google account.

Note

If your organization already uses Zivver, you probably already have a Zivver account. Otherwise, refer to [How to create a Zivver account](https://docs.zivver.com/en/guest/signup-for-zivver.html).

### Install from Google Chrome Web Store

## Log in with workplace information

Depending on the settings chosen by your organization’s Zivver administrator, you may be automatically redirected to your organization’s login page. Enter your workplace credentials on this page to log in.

To stay logged in, select **Remember my credentials for 30 days**. You will remain logged in on this device for 30 days.

You are now logged in to Zivver in Gmail and ready to read and send secure messages. If you do not see the Zivver bar when composing a new message, refresh the page. Contact your organization’s Zivver administrator if you encounter login problems.

## Send a message securely

Make sure you are logged in to Zivver via Gmail:

1. Click _create_ Compose in Gmail.

_A message editor window opens._
2. Compose your message as usual: add recipients, enter a subject, and write your message.
3. _Optional_: Click _attach_file_ **Add attachments** in the lower compose bar to add an attachment (up to 5 TB).
4. Toggle **Secure send** to **ON**.

_If you are sending a Zivver message to a recipient for the first time, you will be asked to set a verification method._

### Security notifications

Your organization has rules in place to ensure that sensitive information is always sent with Zivver. Zivver uses security notifications to inform you when a rule has been triggered.

### Read receipts

You can view a read receipt for each sent message. This way you know who has read your message and who has not. You will find this confirmation as a small envelope icon in the lower left corner of a sent Zivver message. Click the icon to see if the message was opened.

### Message revocation

Zivver messages can be revoked at any time after sending, either for all participants (including the sender) or just for recipients. Message revocation can be scheduled for a set period or occur immediately. Revocation serves two purposes:

- To withdraw a message sent in error.
- To comply with legal or organizational policies requiring that messages not be retained indefinitely.

You can revoke sent messages or set them to expire before or after sending.

#### Set revocation for new messages

1. Click the revoke  icon at the bottom of your message editor.

_A new window titled **Revoke** appears._
2. Click **Revoke for recipients** if you want recipients to lose access to the message.

_OR_

Click **Revoke for everyone** if you want both recipients and yourself to lose access to the message.

Warning

If you choose **Revoke for everyone**, the message becomes inaccessible after the set period. You cannot recover those messages.

3. Click **Revoke in** to revoke the message later

_OR_

Click **Revoke now** to revoke it immediately.

_This option is not available for messages you are still composing._
4. Set a time period using the input box and drop-down selector. Your organization may have set a default period.

_The scheduled revocation date displayed changes according to your selection._
5. Click Revoke.

_If you selected **Revoke in**, a light blue banner appears above the message header showing the revocation period._

_If you selected **Revoke now**, a banner appears stating that access was revoked, and the message background turns gray._

Note

Revoking a message removes it from the Zivver inboxes of all recipients, including those in **CC** and **BCC**.

#### Change revocation settings for sent messages

1. Go to your _send_ **Sent** messages folder in Gmail.
2. Open the message you want to revoke or update. Zivver messages contain the string `[This message is encrypted with Zivver]` in the subject line.
3. Click Edit settings in the top right corner of the message pane.
4. Make changes as needed.
5. Click Revoke.
6. _Optional_: To remove the scheduled revocation, click Reset expiration date.

## Recipient verification

Zivver verifies recipients’ identities by checking whether they possess a preshared secret—usually an access code provided by another means than email. For details, refer to [Verification Methods](https://docs.zivver.com/en/guest/verification-methods.html).

## Personal settings

Click your account in the extension menu to change Zivver settings. See the [Zivver WebApp user manual](https://docs.zivver.com/en/user/webapp/user-manual.html) for more information.

## Business rules

The Zivver Chrome Extension for Gmail monitors the Gmail editor window and may produce [warnings](https://docs.zivver.com/en/admin/webapp/references/business-rules-warning-levels.html) when you add sensitive information or trigger another [business rule](https://docs.zivver.com/en/user/officeplugin/references/business-rules.html). Violations may prevent the client from sending messages through Zivver. Depending on the rule’s warning level, the Send button may be disabled.

To address this:

1. Click  in the top right corner of the editor.

_A window titled **Potential Issues** appears, listing issues and possible actions._
2. Click Ignore to ignore a particular issue.
3. Click Close to close the notification window and return to the editor.
4. Change or remove any elements that triggered the warnings.

## Feedback

Click  in the editor pane to leave feedback, view the documentation, or complete a short survey on your Zivver experience.
