captcha

i had to solve a captcha before i could log in.

the website showed a captcha to verify i was human.

please complete the captcha to submit the form.

the captcha failed, so i tried again.

that captcha was hard to read on my phone.

i refreshed the captcha to get a new image.

the captcha expired after a minute.

our app uses a captcha to prevent spam.

too many captcha prompts slowed down the signup process.

the captcha verification keeps blocking my request.

i entered the captcha code incorrectly and got an error.

they replaced the old captcha with an audio captcha for accessibility.
