Authentication

Cookies

Cookies are the default form of authentication over the majority of Mihoyo APIs. These are used in web events and hoyolab utilities such as the Battle Chronicle. The cookies used in these APIs are the same as the ones you use to log in to your hoyolab account and make payments. This means it's highly recommended to use your own cookies only for local testing and to create alt accounts for actual API requests.

For authentication, you will need to send two cookies: ltuid and ltoken. ltuid is your hoyolab UID and ltoken is a unique token used for the actual authentication.

Setting cookies

There are several ways to set cookies but set_cookies is preferred.

# set as an __init__ parameter
client = genshin.Client({"ltuid": ..., "ltoken": ...})

# set dynamically
client = genshin.Client()
client.set_cookies({"ltuid": ..., "ltoken": ...}) # mapping
client.set_cookies(ltuid=..., ltoken=...) # kwargs
client.set_cookies("ltuid=...; ltoken=...") # cookie header

How can I get my cookies?

From the browser

  1. Go to hoyolab.com.
  2. Login to your account.
  3. Press F12 to open Inspect Mode (ie. Developer Tools).
  4. Go to Application, Cookies, https://www.hoyolab.com.
  5. Copy ltuid and ltoken.

Using username and password

  1. Run python -m genshin login <account> <password>.
  2. Press the Login button and solve a captcha.
  3. Copy cookies.

Setting cookies automatically

For testing, you may want to use your own personal cookies. As long as you are logged into your account on one of your browsers, you can get these dynamically with genshin.utility.get_browser_cookies().

Installation

pip install genshin[cookies,rsa]

Example

# set browser cookies
client = genshin.Client()
client.set_browser_cookies()


# login with username and password
client = genshin.Client()
cookies = client.login_with_password("me@gmail.com", "EheTeNandayo")
print(cookies)

In case of conflicts/errors, you may specify the browser you want to use.

cookies = genshin.utility.get_browser_cookies("chrome")

Details

For some endpoints like redeem_code, you might need to set account_id and cookie_token cookies instead. You can get them by going to genshin.hoyoverse.com.

If you know you will be redeeming gifts and also use other endpoints, you should "complete" your cookies before saving them in for example database with cookies = await genshin.complete_cookies(...)

Authkey

Authkeys are an alternative authentication used mostly for paginators like client.wish_history() and client.transaction_log(). They last only 24 hours, and it's impossible to do any write operations with them. That means authkeys, unlike cookies, are absolutely safe to share.

These authkeys should always be a base64 encoded string and around 1024 characters long.

Setting authkeys

Similar to cookies, you may set authkeys through multiple ways.

# set as an __init__ parameter
client = genshin.Client(authkey="...")

# set dynamically
client.authkey = "..."

Since authkeys are safe to share, all functions which use authkeys also accept them as a parameter.

client = genshin.Client()
async for wish in client.wish_history(authkey="..."):
    pass

PC

Future games can also be found on the same website.

Android

Difficult, check https://gist.github.com/jogerj/2372d0e5bee51e001a6d8956240d527b for more information. If it's no longer valid, utilize Google and search "android genshin impact wish import" or similar.

iOS

No clue, maybe use a sniffer.

Setting authkeys automatically

If you open a wish history or a wish details page in genshin, then the authkey will show up in your logfiles. It's possible to dynamically get the authkey using genshin.utility.get_authkey().

# get the authkey from a logfile
client = genshin.Client()
client.authkey = genshin.utility.get_authkey()

# implicitly set the authkey
client = genshin.Client()
client.set_authkey()
