[BUG] BadCredentials

[hazycora]

Describe the bug Login fails on some accounts on some devices. My current guess is they're doing some kind of A/B test to phase out something this relies on? Maybe the protocol version needs to be updated? Occurs not just here but also on the separate librespot-js project and librespot-java. The bug is not with some library-specific logic but with a change to Spotify- a fix here will likely also be able to be applied everywhere else.

To Reproduce

from librespot.core import Session

session = Session.Builder() \
    .user_pass("username", "password") \
    .create()

Expected behavior The login should be successful.

If it can't be reproduced, I have a server that has this problem, and I'm up for helping in any way I can!

[kokarare1212]

I don't know the details, I suspect that your IP address has been blacklisted due to the number of login attempts?

[hazycora]

given that this occurred the only time I had ever tried on this server, no I don't believe that

[shayanmaher]

I don't know the details, I suspect that your IP address has been blacklisted due to the number of login attempts?

also i have this issue for login auth with this error raise Session.SpotifyAuthenticationException(ap_login_failed) librespot.core.Session.SpotifyAuthenticationException: BadCredentials

[pdtan]

I also got this error sometimes

[shayanmaher]

I also got this error sometimes

i solve this problem it belongs to ip of datacenters which in blacklist popular Datacenters like hetzener,...etc has this problem you can solve this issue by use a fresh ip

[staniel359]

@kokarare1212 I've started to encounter this too.

[IVIanuu]

I also encounter this issue since today.. Any fix?

[phuketbinaryt]

Same issue here with the bad credentials.

[dylenthomas]

This just started happening to me today too, might be an issue with spotify's client? I tried on a MacBook with latest MacOS and my linux desktop, both having same issue. I also tried with the latest install of librespot, that was working yesterday.

Since this is happening to so many people they might have an issue with their api right now?

[clemwo]

I also have this issue on a windows machine.

It's also being discussed in the librespot project directly here : https://github.com/librespot-org/librespot/issues/1308

Feels like spotify changed something on their end maybe?

[rgon]

i solve this problem it belongs to ip of datacenters which in blacklist popular Datacenters like hetzener,...

@shayanmaher happening to me on a residential IP. Definitely not data center blacklisting, but rather seems like a buggy rolled-out deploy in their end or rather some of their pesky A/B API testing

[hazycora]

I also got this error sometimes

i solve this problem it belongs to ip of datacenters which in blacklist popular Datacenters like hetzener,...etc has this problem you can solve this issue by use a fresh ip

this is not true. happens on all residential IPs ive tried now. that was absolutely just part of the rollout.

[TreeOfSelf]

Happening to me as well.

[kokarare1212]

It appears that login using username and password has been discontinued. https://github.com/librespot-org/librespot-java/issues/921#issuecomment-2258440907 Please use other login methods (e.g. zeroconf) or PR a new login method instead.

[staniel359]

@kokarare1212 Could you then provide the instructions on how to use Zeroconf instead of Session?

[realCmdData]

Same issue for me, even changing IP's through a VPN doesn't work.

  File "C:\Users\myusername\AppData\Local\Programs\Python\Python310\lib\site-packages\librespot\core.py", line 1350, in __authenticate_partial
    raise Session.SpotifyAuthenticationException(ap_login_failed)
librespot.core.Session.SpotifyAuthenticationException: BadCredentials

librespot.core.Session.SpotifyAuthenticationException: BadCredentials

UPDATE:

Got it to work... Somehow... Still not quite sure how but I tried restarting my PC and deactivating my VPN, and it worked. Perhaps through trial and error? Or Spotify is blocking CLI requests that come from known VPN servers? I have no idea...

[pdtan]

Please use other login methods (e.g. zeroconf)

Please provide the instructions on how to use Zeroconf instead of Session?

[kokarare1212]

It is incomplete but should work. See the original librespot-java for details.

Sample code can be found here. Sessions within zeroconf should be accessible via these: zeroconf._ZeroconfServer__session

Remember I have very little time to devote to these projects.

Forgive me for jumping in, but you have to actually use the zeroconf server to auth a client before a session will be created. Given the log you provided, it doesn't look like you did that.

[dracarys69]

idk about you guys i can still login fine with email and password and whenever i get BadCredentials issue i delete the credentials json and change my account password and it starts working again. tho its been a while since i had that issue

[g42ftw]

Login with username/password via .user_pass() method is no longer possible: https://github.com/librespot-org/librespot/issues/1308#issuecomment-2276196094

Please provide the instructions on how to use Zeroconf instead of Session?

@pdtan you may use this very sketchy code to generate credentials file to use further. Notice that device running the script should be on the same network as a desktop client in order to transfer playback or/and grab session

Use .stored_file() method instead or .user_pass() on session builder stage to load login credentials from local file:

session = Session.Builder() \
    .stored_file() \
    .create()

It should use credentials.json from current working directory by default.

Cool beans, that works.

Question: do the credentials expire? I want to run librespot in a docker container and maybe transfering playback once would be fine. But if the token expired every few days that would be an issue for me.

[kingosticks]

Reusable credentials do not expire.

[g42ftw]

Question: do the credentials expire?

@clemwo they don't expire, unless you change your password or Spotify does. Successful login with zeroconf should always return the same long-live credentials that .user_pass always did (username+credentials blob).

The Spotify desktop client stores account login data in the client configuration file in a similar way:

.config/Spotify/prefs

autologin.blob="BLOB"
autologin.saved_credentials="{"USERNAME": ["USERNAME", "BLOB"]}"

[pdtan]

@clemwo thanks, but I use credentials.json from start, sometimes BadCredentials still happended, not usual. If using zeroconf to only create credentials.json, I actually don't need it.

RuntimeError IN (test.py, LINE 141 "session = Session.Builder().stored_file().create()"): login_failed {
  error_code: BadCredentials
}

On Windows (this works on Linux) trying to use zeroconf results in the following:

Hello everyone. Tell me if the librespot.core problem has been solved.Session.SpotifyAuthenticationException: BadCredentials Can someone tell me what needs to be done? Thanks for any hints
