I can't enter passwords in Safari 11.1 on macOS 10.13 High Sierra because the last character gets removed

I installed a brand new 10.13 a few days ago. I downloaded it from the App Store and I installed all updates. I'm runnning Safari Version 11.1 (13605.1.33.1.4).

Somehow I managed to log into Google, but I can't log into any other website. Safari does the following when entering text into password fields – on every other webpage except for Google:

• the first character is entered
• after that, it looks like the last character is removed after keyup
• this happens when using the internal or an external keyboard

Normal fields like text, textarea etc. work fine, though.

Here's a gif showing the problem – no Backspace or Shift+Del is pressed. This happens just in Safari – Chrome and Firefox work fine:

I have the following settings:

• autofill: don't store passwords and credit card information
• no extensions are installed
• Adobe Acrobat plug-in is installed

I tried to change the settings and to disable the Arcobat plug-in, but nothing changed.

It seems that macOS’ autocorrection kicks in. I noticed this behavior in a password-field that could be switched to plaintext: Characters get replaced with emojis. For example:

()

… was turned into:

Solution 1:

Finally I got the answer to this annoying problem. I had a configuration in System Preferences / Keyboard / Text to replace 3 big dots ••• with this character: ∴ So every time I typed passwords in Safari, the last 3 characters of the password were replaced with this one ∴ but represented as another big dot since it's a password field. I deleted the substitution configuration and the problem was solved.

Solution 2:

I assumed you checked your accessibility and keyboard preferences. I have had numerous issues with keyboard setting being modified/added during the updates. sticky keys and other settings were modified that I wasn't aware of...I had to start using the manual keyboard viewer until I was able to get it fixed...

.

only other thingi I can think of is trying on an alternate or guest login to see if you have the same problem on a clean user.

I know I am still struggling with my fare share of HSierra simple glitches but I hope you can get this one solved! Good luck!
