ZenyPass is a web application to help you create, store and manage your passwords in a simple and secure way, and to connect more easily to all your accounts.

The password manager ZenyPass is a web application. As such, it is important to configure your web browser correctly to use it in the best conditions.

This document explains:

  • the fundamental principles
  • how to configure Chrome and Firefox web browsers on computers and mobile devices
  • precautions to take when deleting the “cache” memory of these browsers

Things you should know

ZenyPass must store some data directly in your web browser:

  • the data you have entered, saved in encrypted format
  • and some keys used to decrypt this data.

The fact that these keys used to decrypt your data are stored on your devices, not on our servers, guarantees the confidentiality of your data, since these keys are in your sole possession.

To use ZenyPass in a web browser, you must:

  • allow the browser to store data
  • avoid deleting the data stored by the browser

The “private browsing” mode is notably incompatible with ZenyPass, since it does not allow storage of any data, and some care must be taken when erasing the “cache” memory or “cookies”, from the browser itself, or using a tool like Ccleaner (on Windows) or Onyx (on MacOS).

Browsers compatible with ZenyPass include:

  • Google Chrome
  • Firefox
  • Opera
  • Safari
  • Brave
  • Edge Chromium

The default settings are generally compatible with ZenyPass. If you’re having trouble starting ZenyPass, the instructions below explain how to set up the two most-used browsers: Chrome, and Firefox.

Google Chrome configuration for Zenypass

These instructions are based on version 63 of Chrome.

  • Open the settings: enter the address chrome: //settings, or on Windows click on the 3 vertical dots at the top right of the Chrome window then on Settings, or on Mac OS select Chrome> Settings, or “Cmd +,”.
  • Click on Advanced at the bottom of the page.
  • Click on Content Settings …
  • Click on Cookies
  • Configure the first 3 lines as below.

This configuration allows the sites you visit to store cookies in your browser.

If you prefer to block cookies, you can do this by unchecking the first line “Allow sites to save and read cookie data (recommended)”, but you must then explicitly allow the site to save data, adding it in the Allow section at the bottom of this Cookies screen:

  • click on Add in this section
  • type as site name [*.]
  • and click Add

which should give this result:

Firefox configuration for ZenyPass

These instructions are based on Firefox version 57.

Preferences settings

  • Open the preferences: type the address about: preferences, or on Windows click on the 3 horizontal bars at the top right of the Firefox window then on Options, or on MacOS select Firefox> Preferences, or “Cmd +,”.
  • Click on Privacy and Security
  • In the History section, the Firefox will setting should be Remember History, or Use custom settings for history.
  • In this second case, you should also uncheck Always use private browsing mode, check Accept cookies from websites, and uncheck Clear history when Firefox closes, as below.
  • It is also possible to check Clear history when Firefox closes, but in this case, it is also necessary to click on Settings… at the end of this line, then you can check all the boxes under the section History, but do not check boxes under Data, as below.

First connection to ZenyPass

When connecting to ZenyPass for the first time, Firefox may ask permission to store data. If this is the case, check Remember this decision, and click Allow.

Clearing browser data cache memory

If you want to delete the navigation data from Chrome or Firefox, it is not possible to specify to delete everything except the data from ZenyPass. It is therefore necessary to keep all cookies/site data of the browser. It is however possible to clear the cache memory, and the navigation history.

In Chrome as in Firefox, it is therefore necessary to uncheck the deletion of Cookies and site data as below:


Use another device authorized to connect to your ZenyPass account to recover deleted data

For better security, we recommend that you allow access to your ZenyPass account from multiple devices. If the data stored by a web browser is erased by mistake, or because of a misconfiguration, it is still possible to allow this browser to connect to ZenyPass again from another authorized device, and doing so, automatically synchronize again all the data saved in the account.

This feature is also useful when a device is lost or replaced. Granting access to your ZenyPass account from a new device will automatically transfer all your data to this device.

Using Ccleaner (Windows)

The use of computer cleaning tools, such as Ccleaner for Windows, or Onyx for MacOS must be done with caution.

It is possible to tell Ccleaner to keep ZenyPass data following these few steps:

  • open Ccleaner
  • click Options
  • click on Cookies
  • type zenyway in the Cookies on Computer search box
  • click on
  • click on the right arrow to add in the Cookies to Keep column

Using Onyx (MacOS)

Onyx does not allow, as Ccleaner, to add exceptions on cookies to erase. We therefore recommend that you do not delete cookies with Onyx. For this, in the Cleaning> Internet tab, you have to uncheck Cookies.

If you delete cookies via Onyx, your account will no longer be accessible on the browsers of this device. But you can allow these browsers to access your account again, from another authorized device, to retrieve all of your data.

Special case of Chrome and Firefox on tablets and smartphones

The mobile versions of Chrome and Firefox do not offer as many cookies settings. Cookies need to be allowed, and the “private browsing” mode cannot be used, which should be the default settings.

If you want to erase browsing data on mobile versions of Chrome or Firefox, you can not specify that you want to erase everything except the ZenyPass data. It is therefore necessary to keep all the cookies.

For Chrome, you must apply the following configuration:

For Firefox, you must apply the following configuration:

If you still want to erase all data from these browsers, you can do so, then allow these browsers to access your account again, from another authorized device, to retrieve all your data.
