Need to store passwords, tokens, or other sensitive values in a Capacitor app without rolling your own encryption? The [Capacitor Secure Preferences plugin](/docs/sdks/capacitor/secure-preferences/) is a drop-in replacement for the official [Capacitor Preferences](https://capacitorjs.com/docs/apis/preferences) plugin that stores key/value pairs securely. It provides cross-platform support for Android, iOS, and Web and is available to all Capawesome [Insiders](/docs/insiders/). Let's take a quick look at the [API](/docs/sdks/capacitor/secure-preferences/#api) and how to use the plugin in your Capacitor app. ## Installation[ΒΆ](#installation "Permanent link") To install the Capacitor Secure Preferences plugin, please refer to the [Installation](/docs/sdks/capacitor/secure-preferences/#installation) section in the plugin documentation. ## Usage[ΒΆ](#usage "Permanent link") Let's take a look at the basic usage of the plugin. You can find the complete API reference in the [API](/docs/sdks/capacitor/secure-preferences/#api) section of the documentation. ### Set a value[ΒΆ](#set-a-value "Permanent link") You can set a value using the [set](/docs/sdks/capacitor/secure-preferences/#set) method: `[](#%5F%5Fcodelineno-0-1)import { SecurePreferences } from '@capawesome-team/capacitor-secure-preferences'; [](#%5F%5Fcodelineno-0-2) [](#%5F%5Fcodelineno-0-3)const set = async () => { [](#%5F%5Fcodelineno-0-4) await SecurePreferences.set({ [](#%5F%5Fcodelineno-0-5) key: 'password', [](#%5F%5Fcodelineno-0-6) value: '123456', [](#%5F%5Fcodelineno-0-7) }); [](#%5F%5Fcodelineno-0-8)}; ` The stored value can be any string. To store other types or more complex objects, you can use [JSON.stringify()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global%5FObjects/ JSON/stringify) to convert them to a string before storing them and [JSON.parse()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global%5FObjects/JSON/parse) to convert them back to their original form after retrieving them. No encryption on Web On **Android** and **iOS**, the value will be encrypted and stored securely on the device. On **Web**, the value will be stored unencrypted in `localStorage` since the web platform does not provide a secure storage solution. This is for development purposes only and should not be used in production. ### Get a value[ΒΆ](#get-a-value "Permanent link") You can get a value using the [get](/docs/sdks/capacitor/secure-preferences/#get) method: `[](#%5F%5Fcodelineno-1-1)import { SecurePreferences } from '@capawesome-team/capacitor-secure-preferences'; [](#%5F%5Fcodelineno-1-2) [](#%5F%5Fcodelineno-1-3)const get = async () => { [](#%5F%5Fcodelineno-1-4) const { value } = await SecurePreferences.get({ key: 'password' }); [](#%5F%5Fcodelineno-1-5) console.log(value); // 123456 [](#%5F%5Fcodelineno-1-6)}; ` This will decrypt the value and return it as a string. ### Remove a value[ΒΆ](#remove-a-value "Permanent link") To remove a value, you can use the [remove](/docs/sdks/capacitor/secure-preferences/#remove) method: `[](#%5F%5Fcodelineno-2-1)import { SecurePreferences } from '@capawesome-team/capacitor-secure-preferences'; [](#%5F%5Fcodelineno-2-2) [](#%5F%5Fcodelineno-2-3)const remove = async () => { [](#%5F%5Fcodelineno-2-4) await SecurePreferences.remove({ key: 'password' }); [](#%5F%5Fcodelineno-2-5)}; ` ### Clear all values[ΒΆ](#clear-all-values "Permanent link") If you want to clear all values, simply call the [clear](/docs/sdks/capacitor/secure-preferences/#clear) method: `[](#%5F%5Fcodelineno-3-1)import { SecurePreferences } from '@capawesome-team/capacitor-secure-preferences'; [](#%5F%5Fcodelineno-3-2) [](#%5F%5Fcodelineno-3-3)const clear = async () => { [](#%5F%5Fcodelineno-3-4) await SecurePreferences.clear(); [](#%5F%5Fcodelineno-3-5)}; ` ### Get all keys[ΒΆ](#get-all-keys "Permanent link") And finally, if you want to get all stored keys, you can use the [keys](/docs/sdks/capacitor/secure-preferences/#keys) method: `[](#%5F%5Fcodelineno-4-1)import { SecurePreferences } from '@capawesome-team/capacitor-secure-preferences'; [](#%5F%5Fcodelineno-4-2) [](#%5F%5Fcodelineno-4-3)const getAllKeys = async () => { [](#%5F%5Fcodelineno-4-4) const { keys } = await SecurePreferences.keys(); [](#%5F%5Fcodelineno-4-5) console.log(keys); // ['password'] [](#%5F%5Fcodelineno-4-6)}; ` ## FAQ[ΒΆ](#faq "Permanent link") ### Which platforms does the Capacitor Secure Preferences plugin support?[ΒΆ](#which-platforms-does-the-capacitor-secure-preferences-plugin-support "Permanent link") The plugin supports Android, iOS, and the Web. On Android and iOS values are encrypted and stored securely; on the Web they fall back to unencrypted `localStorage` (see below). ### Is the stored data encrypted on every platform?[ΒΆ](#is-the-stored-data-encrypted-on-every-platform "Permanent link") No. On **Android** and **iOS** values are encrypted and stored securely on the device. On the **Web** there is no secure storage API, so values are kept unencrypted in `localStorage` β€” intended for development only, not production. ### Is it a drop-in replacement for @capacitor/preferences?[ΒΆ](#is-it-a-drop-in-replacement-for-capacitorpreferences "Permanent link") Yes. It mirrors the official [Capacitor Preferences](https://capacitorjs.com/docs/apis/preferences) API β€” `set`, `get`, `remove`, `clear`, and `keys` β€” so you can swap it in with minimal changes. ### Can I store objects instead of plain strings?[ΒΆ](#can-i-store-objects-instead-of-plain-strings "Permanent link") Values are stored as strings. Use `JSON.stringify()` before storing an object and `JSON.parse()` after reading it back. ## Related Posts[ΒΆ](#related-posts "Permanent link") * [Alternative to the Ionic Identity Vault plugin](/blog/alternative-to-ionic-identity-vault-plugin/) * [Alternative to the Ionic Secure Storage plugin](/blog/alternative-to-ionic-secure-storage-plugin/) * [Exploring the Capacitor Secure Preferences API](/blog/exploring-the-capacitor-secure-preferences-api/) * [Capacitor Biometrics plugin: Face & fingerprint authentication](/blog/announcing-the-capacitor-biometrics-plugin/) * [Capacitor Vault plugin: store secrets securely](/blog/announcing-the-capacitor-vault-plugin/) ## Conclusion[ΒΆ](#conclusion "Permanent link") The [Capacitor Secure Preferences plugin](/docs/sdks/capacitor/secure-preferences/) gives you encrypted key/value storage on Android and iOS behind the familiar Preferences API, so securing tokens and other sensitive values is mostly a matter of swapping the import.
