SwiftKey is designed never to learn from or predict what you enter in a password text field. However, if you have sent an SMS message with your password to someone in the past, or typed your password in an email or normal text field with SwiftKey, it may be remembered by the prediction engine. It may also be the case that a website or app did not correctly inform SwiftKey that a particular field was a password field.

If you find your password is being predicted, you can easily remove the word from SwiftKey’s dynamic language model by long-pressing on the prediction when it is shown and tapping ‘Remove’.
