What's the difference between 'log in' and 'log into'?

'Log in' can stand alone (I need to log in) or use 'to' before the system (log in to Jira). 'Log into' combines them—always followed by the system you're accessing (log into Jira). Both are correct.

Is 'login' one word or two?

As a verb, use two words: 'log in' or 'log into.' As a noun or adjective, use one word: 'your login credentials' or 'the login page.'

Can I say 'sign in' instead of 'log in'?

Yes, they mean the same thing. 'Sign in' is common for consumer services like Google or Microsoft. 'Log in' is more common in technical contexts like servers and internal tools.

What's the past tense of 'log into'?

The past tense is 'logged into.' Example: 'I logged into the staging server and found the bug.'

Is 'log on' the same as 'log in'?

'Log on' is older and less common now. 'Log in' or 'log into' is the standard in modern tech. Some older systems still say 'log on' but it means the same thing.

How do I use 'log into' in a Jira ticket?

Use it in reproduction steps: 'Log into the application with test credentials, navigate to Settings, and click Export.' It's clear and professional.
