This Tech 101 article explains the functions of Keychain in macOS Sierra as well as how to access and edit Keychain files. What Does Keychain Store? Keychains were originally developed in the early 1990s for use with an Apple email system called PowerTalk. Keychain is the password management system in macOS, developed by Apple.It was introduced with Mac OS 8.6, and has been included in all subsequent versions of the operating system, now known as macOS.A Keychain can contain various types of data: passwords (for websites, FTP servers, SSH accounts, network shares, wireless networks, groupware applications, encrypted disk images), private.
If you’re seeing strange problems with passwords on your Mac—such as having to enter the same Wi-Fi network password every single time you try to connect—it’s possible that something’s wrong with your keychain. Keychains are a part of the Mac's system of storing passwords and other sensitive data and controlling access to that stuff. You know how your computer will ask you if you'd like to save a password into your keychain? That's so you don't have to keep typing it in. It'd be a bummer if Apple Mail made you enter in all of your email account passwords whenever you needed to send a message.
Anyway, the program that controls all of the keychains (and thus the stored passwords) that you have is called Keychain Access, so that's where we'll do our troubleshooting for the purposes of this tip.
One of the common symptoms of a potential keychain issue is this familiar but incredibly annoying alert from Mail, especially if you start seeing it all of the time:
Dark theme for macos high sierra 10.13.6. Of course, that box can mean tons of things, from network or server troubles to your password actually being incorrect (surprise!), but it can also indicate that something's wrong with the keychain entry that's storing that password. To check it out, first open the aforementioned Keychain Access program, which lives in your Applications> Utilities folder.
Here's its pretty little icon. Tango for mac os x.
Once it’s open, click on the 'Keychain Access' menu in the upper-left corner and choose Keychain First Aid.
In the window that appears, you’ve only got two options—'Verify' and 'Repair.' If you just wanna see if anything’s wrong, click 'Verify,' type in your account password, and then choose Start. If you’d like to fix problems as they're found, select 'Repair' instead. Pretty self-explanatory, right? Seagate ntfs for mac high sierra.
Whew!
If the program finds and fixes anything, try doing whatever caused you to want to repair your keychain in the first place and see if the issue’s been resolved. If not (or if the First Aid tool didn’t find anything, which is quite common), you can try some more serious steps, like searching for any keychain entries that are associated with the problem and removing them manually. https://babeskyey875.weebly.com/best-terminal-apps-for-os-x.html. So for example, if we pretend I've got a troublesome Gmail account that keeps prompting me for my password within Apple Mail, I can search Keychain Access for 'Gmail' and see what comes up:
That's…um, only about a twentieth of what's actually there. I have a lot of Gmail accounts.
I could then select some or all of those entries and press the Delete key to get rid of them, or I could double-click each one to see more details about what's stored there. If I delete an entry, Mail will request the missing password again (since Keychain Access no longer has it stored), and when I re-enter it, a new keychain item will be created. So if the problem is with one particular entry, that's an easy way to troubleshoot things.

Keychain First Aid For Macos Sierra Update
Finally, if you're having tons of issues, a nuke-it-from-orbit solution would be to reset your entire keychain. Apple’s got a support article on that, but I really really really don’t recommend you follow those instructions unless you know what you’re getting into and you’ve got some serious problems with your keychain. If I didn’t say “really” enough there, let me do it some more. Be really really really careful with that, OK?
