ios 15 not remembering account passwords

EdHans comment to change the timezone in iCloud.com has fixed the issue for me. I have not encountered it since making the change.

I resolved this - I had to remove the email account and re-add it. I have not had a failure since I did this.

iOS 15.1 update seemed to have fixed the problem with the password for Exhange. Haven't has to re-enter the password since the update.

Hello and welcome to Apple Support Communities EdHans,

Thank you for contacting us. We can definitely take a look at this with you. As we understand it, you're passwords are not auto filling? We can understand why you’d reach out for a solution. To start, we want to confirm iCloud Keychain is turned on for all your devices. Additionally,  we want to clarify if they are stored in your iCloud Keychain, and if so, if there is a security recommendation on the ones that are giving you an issue? Start with the troubleshooting here: If iCloud Keychain won't turn on or sync

Thank you for contacting Apple Support Communities.

Best regards.

EdHans,

Thanks for that. We investigated further after your hotmail suggestion. We would like you to check the settings on the phone and see if the below settings are the same:

Mail settings Hotmail. (FYI, Same for Outlook)

POP / IMAP imap

Incoming server: outlook.office365.com

Incoming port: 993

SSl (security) incoming: ssl

Outgoing server: smtp.office365.com

Outgoing port: 587

Requires sign-in: yes

This is the step by step guide recommended, and they are saying to confirm it after creating it, then restarting the device. That just may be the key for your situation.

iPhone guide to setup Hotmail mail

Open 'Settings', click on 'Passwords & accounts' and 'Add account'.

Under 'Outgoing mail server' enter the details below and choose 'next':

Hostname: smtp.office365.com

Make sure 'Email' is checked and click 'Save'.

Your email account is now saved. In the next steps we check if all settings are correct.

Click on your newly created email address and choose 'Advanced'.

Make sure that the following data is

correct under 'Incoming server':

Use SSL: on

Go back to the previous screen and under 'Outgoing server' click on smtp.office365.com.

Make sure the following information is correct:

We hope we finally found a solution for you. If you still continue to need assistance after that, please get in touch with Apple Support directly next: Get Support

Changing the time zone in icloud.com worked for me. The screen said it was central but once I drilled down to change it it was set to pacific. This may not work for everyone but it I have not had to enter my password today. I used to have to update it everyday and I could tell it wasn't saving my password because I had recently added a letter to it and when I went into the mail account my password was missing a letter. This was only on my work outlook email on the mail app in my iphone. My gmail was working fine.

iphone 12 pro 15.0.2

For me 15.1 solved all problems

I MAY have found the issue. It has been almost 24 hours since I changed it and I haven’t received the pop up telling me that my Exchange password is incorrect. Go to iCloud.com in Safari and check your time zone setting. Mine was set to Pacific which is INCORRECT and must have gotten changed during the iOS 15 update. I set it to the correct Eastern time zone and no pop up so far in the last 22 hours. It’s worth a try and needs to be corrected anyway if it is wrong like mine was. See screenshot below.

I had to delete Exchange from the phone mail app and download the outlook app.

it’s working now, I just have to two mail/calendar/contacts apps right now.

hopefully they will fix it soon and I can have it all in one place again.

on the plus side… I can look at my personal email without those pesky work e-mail’s gabbing my attention!! LOL!

EdHans,

Thank you for your response and updated information. Okay, we see where this is happening, and you stated Outlook. Is your Outlook email the same as your Apple ID? If so, it may require an app specific password. We recommend giving that a try and then doing a backup and see if that resolves your issue.

Using app-specific passwords:"App-specific passwords are passwords for your Apple ID that let you sign in to your account and securely access the information you store in iCloud from a third-party app. For example, use app-specific passwords with mail, contacts, and calendar services not provided by Apple. App-specific passwords maintain a high level of security and help ensure your Apple ID password won’t be collected or stored by any third-party apps you use."

If you need further assistance after following the link above, please don't hesitate to reach out.

Thank you for contacting Apple Support Communities.

Best regards.

I am in New Zealand and it was set to PST. Hopefully this fixes the password issue with Exchange.

IOS 15 seems to be the most buggy update from Apple in a while getting lots of issues not just this one

I have the same issue with my exchange email account after update to OOS 15 (also 15.02). Every morning I have to reenter the password. No problem with my gmx account. I am living in Germany and I have an Iphone XR.

This is definitely a bug in IOS 15 in connection with a MS Exchange account.
