n26keychain uses system keyring as a storage for persisting/getting credentials and token. It supports OS X, Linux (dbus) and Windows.

Prerequisites

• Go >= 1.14

Install

go get github.com/nhatthm/n26keychain

Usage

n26api.CredentialsProvider

Examples

Build n26api.Client:

package mypackage

import (
	"github.com/nhatthm/n26api"
	"github.com/nhatthm/n26keychain"
)

func buildClient() (*n26api.Client, error) {
	cred, err := n26keychain.Credentials()
	if err != nil {
		return nil, err
	}

	c := n26api.NewClient(
		n26api.WithCredentialsProvider(cred),
	)

	return c, nil
}

Persist credentials in system keyring:

package mypackage

import "github.com/nhatthm/n26keychain"

func persist(username, password string) error {
	return n26keychain.PersistCredentials(username, password)
}

auth.TokenStorage

package mypackage

import (
	"github.com/nhatthm/n26api"
	"github.com/nhatthm/n26keychain"
)

func buildClient() *n26api.Client {
	return n26api.NewClient(
		n26keychain.WithTokenStorage(),
	)
}
