This FAQ contains questions about login, account creation, account page, password, OpenID, and registration to a data access control group.
Each ESGF question is sorted into exactly one topic. See also ESGF General since questions of general interest and questions matching several topics are under topic ESGF General.
You don't need an account to search for data on a public project. You will need an account to download data. You should get an account on the node you wish to download data from.
You only need to join the project if you plan to edit wiki pages, upload files etc. In case you want to download data from ESGF, you will most likely have to join a data access control group. These groups are not the same as CoG projects. For details about data access groups see tutorial Authorization for ESGF Data Access.

Normally, group memberships are shown on your User Profile. User Profiles and group registration are related to an account, not a person. You may have registered for group access using a different account or an account created before the 2015 ESGF overhaul, that no longer exists.
Example of the warning from FireFox
ESGF uses a self-signed certificate. You have to tell your browser to accept this non-commerical certificate. Each browser does this differently. Here is a table of tutorials:
|Get Safari to accept the ESGF certificate|
|Get Chrome or Aviator to accept the ESGF certificate|
|Get Internet Explorer to accept the ESGF certificate|
|Get Firefox to accept the ESGF certificate|
This error means your ESGF cookie is corrupted.
Solution 1: To get a new cookie you will need to clear your cache, close your browser, and try logging in again.
Solution 2: Open a private window. Firefox will not remember its cookies in this window.
That project may not be serving any data or they have turned off the widget and instead have a link somewhere on the page to the search area.
Example error message (with Firefox):
pcmdi.llnl.gov has been renamed to esgf-node.llnl.gov; use https://esgf-node.llnl.gov/esgf-idp/openid/your_account_name instead of https://pcmdi.llnl.gov/esgf-idp/openid/your_account_name
Instead, I'm getting an error "Error: unable to resolve OpenID identifier" or I'm guided to a Group Registration Request page and, after pressing "Register", I'm getting a "HTTP Status 500".
Most ESGF partners do not maintain accounts from before the ESGF overhaul. The same may be true for accounts created on test nodes during the overhaul (June 2015 - January 2016). These include OpenIDs from pcmdi9 and esg-dev.
Please create a new account on an ESGF node of your choice. Your new account should be accepted by every ESGF portal and ESGF data nodes. Note to change your password and account information, you must login into the ESGF node you created the account on. Also register to the data access control groups again, e.g. CMIP5 Research or CMIP5 Commercial (for download of CMIP5 data).
This could be either a problem with the user account, or with the server setup where the user registered:
The server which issued the OpenID was retired or now has a different name, e.g. pcmdi3, pcmdi9 and pcmdi.llnl.gov were changed to esgf-node.llnl.gov and esgf-node.ipsl.fr was changed to esgf-node.ipsl.upmc.fr. If you have an OpenID https://pcmdi.llnl.gov/esgf-idp/openid/your_username, simply use https://esgf-node.llnl.gov/esgf-idp/openid/your_username instead. In all other cases, the old OpenIDs are no longer valid. Create a new OpenID at the ESGF node of your choice.
Instead Firefox uses an old OpenID.
Did a message appear in the same Firefox session whether to use your credials imported into your browser? Please respond that query with pressing "cancel" since an old OpenID may have been assigned to your credential. This can even happen in a private window.
ESGF does not require the user to reply to any confirmation email. You can immediately use your new account.
